The product looks very nice, especially with the rgb lighting, but I believe the one we received is defective. With some of our cartridges it does not work at all, and for the ones that it does, it only works on the highest setting with a ton of preheating (still doesn’t work sometimes, we tried charging it). I really want to like it because of the design and the size, but it simply doesn’t work very well, and the build quality is generally quite cheap on it as well. All of the plastic is very thin, and the cart is easily budged from it’s correct position. I might give one another shot, but likely not.
