This is so great, I recommended it to my friend and they got it too. I have a 3D printer, but some things are better suited freehand. This allows you to break free of restraints of build plate restraints and allows you to do things that may fail on a printer because you can vary the control yourself, like a vertical standing string. There is a learning curve, you will definitely need more filament. I really like that this allows temperature settings for abs and pla. I can make 2 flat objects and then join them at off angles which I really like to create true 3d objects with ease. This of course comes at the cost of it only being as accurate as your hand moves. I suggest starting with the speed at the lowest level. Play with the temperature if needed. I suggest buying a roll of 20$ Pla filament for 3d printers like hatchbox unless you want the color variety. Then buy a 3d pen variety kit, but it will be more expensive. I was nervous about the temperature, but in reality, I can touch the filament as it just came out of the tip. I made a stand as my first project to hold the pen, but it turns out, letting sit flat on the silicone mat worked fine. The fresh pla was hot but wont leave a burn. The speed control, temperature control, and ease of use is amazing. Beware the chord is kinda short, i used it about 4ft from the plug, you may need an extension chord. The box it came in was packaged so nice! You’ll want a pair of tiny precision wire snips to cut off excess drool from your print, since as you pull away it will leave strings. I also got the myint doodle pad which was nice but not necessary to make precise shapes. I found the prints sometimes cooled and peeled off my surface. Using masking tape helped it adhere better, as is the same with 3d printing. If its an issue for someone, I wonder if some sort of mild heated bed would work, like a beverage heater..? I find in my use, the nozzle gets covered in the filament as I rub it around, so I bought a brush set from the dollar store and it works perfect to brush off the filament while the tips hot to keep it clean. I had to switch from red to green and it was very easy to change filament, both by unloading and by just following up. Be sure to read the little manual. I have never got a clog yet. By loading directly, I did get a weird color, with red and green it wasn’t pretty, but I could see this being useful in applications to change colors often and create beautiful effects, although that is likely not recommended since it could cause clogs. The pen fits nicely in my hand and is easy to manipulate. I was worried it would be big, but it is just right.
