AIO Robotics Full-Metal Premium 3D Printing Pen for 3D Modeling, Education, PLA Filament Support, bright OLED-Display

Ok, I first wrote the following review -"This product is nice, but NOT durable, thus not worth the money. For us this product lasted two months before dying. During the two months it was used carefully and moderately. Estimated usage time was 7 hours. So for the $50.00 spent that's about $7.14 per an hour not including materials. So essentially assume $10.00 an hour. In talking to other users, I realize we were lucky that it lasted too long. Generally, the first thing to fail is the heat intake."However, I wrote this too hastily. I had reached out to AIO and had not heard back when I wrote this review. Then the AIO customer service folks wrote back and said they were sorry that the unit had failed and offered to replace the unit ASAP. The service representative, Jens Windau, was polite, responsive, clear and thorough. The replacement procedure was easy to follow.It's not often when a company takes responsibility for a faulty product and does an outstanding job to make sure that a customer has a good experience after a problem. AIO Robotics is one of those rare companies that is on it's way to being great. \Thank you AIO.

So this is my first time playing with 3d printing using the pen format other than a few that I checked out at SF Maker Faire and I have to say I am loving it so far!I was super impressed with not only the packaging but the overall style, weight and ease of this pen...I literally had it out of the box with instructions read and 1st test project completed in about 10 minutes!The pen itself feels solid, well made and perfectly balanced. After plugging it into the power cord it took about 3-4 minutes to reach its target 180°c heat and although I had worried that I would feel the heat while holding the pen, I really didn't feel it was too hot, just slightly warm.The feed buttons were smartly placed near the bottom, and I totally loved how easy it was to start and stop the filliment flow as I was printing as there were a few times I needed to move to a different area and didn't want to waste the filliment while re-adjusting.There will definately be a learning curve for people to get used to the manual start and stop clicking so be prepared to make a few mess puddles until you figure out the way you can hold it most comfortably to keep the buttons easily accessible.I decided to try changing the filliment during my little house print and was impressed with how easy it was. I don't know why I was thinking it would make a stringy mess or be harder than it was, but clearly I overthought the process because it was super easy and I was able to switch from the blue to the white test filaments and back again in less than a minute without waiting for it to reheat.Overall I am very satisfied and impressed with this little pen and looking forward to building up my steady hand printing skills and seeing what I can come up with as well as exploring more of the AIO products (I have been loving the 3d scanner/printer since it's debut a few years ago at Maker Maker faire and hope I can get that one day soon!)Also I would like to give a big Kudos to the support at the AIO company who were super helpful and very quick at returning my emails extremely promptly...They answered any questions I had, we're super helpful, informative and knowledgeable about their products and went above and beyond in the service department which is ridiculously hard to come by these days, so a big THANK YOU to them for setting the bar high for those other comparable companies!

I've been enjoying this pen for about two weeks. I wanted to really get it running before I posted a full review.I own a 3d printer, and I have a ton of filament for it. As such, I thought a 3D pen would be a cool little toy to use some of the filament. It turned out to be so much better than even that.I use it to prototype some drawings, and I like to draw full structures. I enjoy the pyramid designs, and once you watch 3d printing for a time, you have a good idea of how to do 'bridges' and such. This pen holds up to everything it needed to do. Worked with every type of PLA I had around me, was very quick to heat up, and held to a very consistent speed. The 5 speeds are fantastic, and really do allow for various levels of drawing.Would highly recommend this pen.
