G Pen shoppers are deeply divided. Satisfied customers praise the products for delivering on their promises, highlighting smooth ordering experiences and straightforward operation and maintenance. However, a substantial portion of reviewers report serious issues: defective tanks that fail within months despite proper care, requiring expensive replacements; unresponsive or dismissive customer service when addressing defects; and aggressive marketing tactics that offer better deals immediately after purchase to create buyer's remorse.

The company's refusal to honor refunds for defective items and the high cost of replacement components (over $20 including shipping) are recurring frustrations. While some buyers are satisfied with their purchases, the pattern of product durability problems and poor customer support resolution suggests significant reliability concerns that potential buyers should consider before ordering.

Tyler R.Mar 26, 2026

I find it frustrating seeing people bash products that just aren't right for them personally. G-Pen absolutely deserves better than a three star rating. My whole experience from ordering to receiving was incredibly smooth. Even during that massive snow storm last week the package only ended up being delayed by a day instead of arriving early like it normally would. And here's the thing about my consumables order - they got to me in two days with no shipping charge. That's wild. My Hyer device has been working without a single issue since I got it. Already planning to grab the dry herb attachment next. Thanks for the great service. Hopefully we can get that rating higher.

Marcus T.Dec 19, 2025

This G-PEN delivers exactly what it promises. Everything works as advertised. Really happy with my purchase.

Patricia L.Aug 7, 2025

GPen pulls shady marketing tactics where they offer you a better deal right after you already paid for something. Seriously though, literally a few minutes after I finished checking out they texted me saying there's a sweeter deal available but oops, too late for that now. That's just wrong.

Michael S.Mar 26, 2025

The tank design on the G pen micro+ is really poor. I've gone through two replacement tanks and both failed on me. You can keep it spotless and it still falls apart. They last a couple months and then stop working, flashing red and green lights before dying completely. Getting a new tank with shipping costs me twenty three bucks every time, which adds up quick. Find a better product.

Sarah M.Dec 29, 2024

The GPen Micro + Vaporizer for concentrates has been fantastic for what I need. I'm really impressed with how straightforward everything is - charging it up, putting in product, operating it, and keeping it clean are all super simple. Thinking about grabbing a few more to give to friends as gifts. Top notch product overall.

Brandon J.Dec 22, 2024

This has got to be the worst customer service experience I've ever had with any company. I received the G pen micro concentrate vaporizer and it was completely unusable right out of the box. I contacted them within minutes of opening the package, told them I wasn't happy and wanted a refund. They flat out refused, claiming it was already used. The thing tasted like burnt chemicals and had a weird electrical taste. They told me to run a burnout cycle to fix it. I explained that any legit company should be doing those burnouts before shipping so customers don't have to breathe in toxic fumes. I did what they suggested anyway but it didn't help and I wasted some good product trying. They took fifty bucks from me and I got lucky compared to people on here who spent way more. This is honestly on me for not looking into reviews first. If you're thinking about ordering from this site, just know there's a real possibility you're going to feel like you threw your money in the garbage. That's exactly what happened to me and seems like it's happening to tons of other people too. Terrible quality items and even more terrible customer support.

Christopher B.Nov 30, 2023

I bought the Gpen roam and it clogs every single use, taking forever to clean. This makes it pretty much unusable and definitely not something you can carry around easily. I tried posting a negative review on their site but they only accept positive ones. Be careful of any company that won't let customers leave honest feedback online.

Lauren W.Nov 28, 2023

Absolutely amazing service. I bought something during a Black Friday promotion but realized on the following Monday that I'd picked the wrong item. Total mistake on my end. Since I hadn't gotten shipping confirmation yet, I figured I might as well email and ask if canceling or changing my order was possible. Honestly I thought they'd say no way, but it was worth asking. They actually said yes and processed the refund immediately. My partner ended up ordering the correct item I wanted so we got our Cyber Monday discount anyway. Really grateful for this. Not many companies are willing to cancel orders at all, and I was totally prepared for them to turn me down. They went above and beyond and it genuinely made my day and helped my bank account. Can't wait to try out the GPen Roam. Might try ordering that other device someday too, hopefully on purpose this time.

Nathan G.Jun 13, 2022

Never had worse customer service in my life. My product was out of stock but nobody let me know. I waited over thirty days and they just canceled it without even telling me. When I finally called to ask what happened they were genuinely rude about the whole thing. Honestly one of the worst experiences ever, especially for 2022.

Jennifer H.Feb 7, 2022

The mouthpiece gets way too hot and can actually burn your lips. The device cuts off after five minutes which isn't nearly enough time to finish the herbs loaded in there. The mouthpiece opening is a pain to clean out and the material started breaking down immediately after one session. The temperature settings don't seem to match what they claim either. The portable size is nice and the idea behind it is solid, but they really need better engineering on this thing.

Robert K.Jan 24, 2022

I used to be a huge fan of my G-Pen device. The thing performed amazingly. Dropped $75 on it up here in Maine and felt like I was getting quality equipment. That changed once I started maintaining it regularly. When using thicker materials the unit would clog up and I'd have to clean it after every couple sessions. After about eight weeks of use, the ceramic component in the mouthpiece cracked from all the cleaning cycles. I reached out to customer service multiple times trying to figure out options. Could they send me a replacement ceramic piece? Was there a discount code to buy one? Could they offer any guidance on repairs? The response I got back was basically too bad. Legal complications, they said. No replacement parts available. No discount offered. No suggestions on fixing it. After going back and forth twice they basically said I was out of luck. I tried explaining that seventy five dollars was significant money for me and I was just trying to maintain the device. They weren't interested in helping. I'm on a fixed income and can't justify dropping another seventy five dollars on a new unit just because the cleaning caused a component to fail. It's disappointing that they won't stand by their products. Regular folks like me don't have unlimited budgets to replace things whenever they break. I really hope they'll reconsider their approach to customer support and warranty issues. I got nothing but silence and rejection. That's a pretty terrible way to treat your customers. Don't recommend buying from them.

Jessica N.Jan 21, 2022

I wish I'd done more homework before ordering from this outfit. Their website looks totally legit and professional. I put a G Pen in my cart on January seventh and got a message saying if I bought right then it would go out quickly, but otherwise there'd be delays from January eighth through the nineteenth. I believed it and went ahead. My order confirmation said it would ship soon but also mentioned delays due to current conditions with a ten to fourteen day wait. I wasn't thrilled but figured I should trust what the system told me. Two weeks passed and I was fed up, especially since I had travel plans coming up. I couldn't get a shipping date from anyone on their support team. After looking at what other people said online, I discovered that shipping problems and poor customer service happened constantly no matter the time of year. Really disappointing. I sent them an email with no response. Tried messaging them on Twitter since they were still posting, nothing. Got on their live chat and finally just canceled the whole thing. The actual product might be solid but dealing with getting it to your door is a nightmare.

William T.Jul 14, 2021

Bought an item for one hundred eighty dollars. It's been almost a month and I still don't have it or my money back. When I contacted Grenco Science they keep telling me it shipped but can't issue a refund until the item arrives. It supposedly shipped but there are no tracking updates. Ordered mid-June, writing this in mid-July. Do not buy from them. Customer service is absolutely terrible.

Kevin D.Aug 24, 2020

Grenco Science basically scammed me out of my money. I spent over two hundred dollars on their Gpen Gio products and they're straight up refusing to ship what I ordered. All I get are excuses and the runaround when I try to email them for answers. Grenco Science, just send my stuff already.

David C.May 4, 2020

I placed an order on April 28th. When I checked in on May 4th asking where it was since I'd paid extra for expedited shipping, they told me to expect another week and a half wait. That's completely unacceptable. Their website doesn't mention anything about shipping delays, only customer service delays, and they won't pick up the phone. I'm giving them a one star because they couldn't even bother to notify me about the holdup on something I'd already paid for.
