[EX Q]: First of all, they took a long time to get to me. They come with no instructions. No way of knowing when they are fully charged. Charge doesn't last long, at all. And they scratch very easily. Very disappointed with this product unfortunately.
[EX A]: negative

[EX Q]: After reading reviews, I thought I would order 2 sizes up. Normally I’m a L/XL, so I purchased a 2X figuring it would fit! To my surprise, the shirt was way too small. It fits my sister who is a size small. The material was not cotton as I thought, but 95% spandex. I’m very disappointed as the shirt is very cute. Instead of returning it, I gave it to my sister. I would recommend ordering 3 or more sizes up from what you normally wear.
[EX A]: negative

[EX Q]: This product stopped working less than 200 hours of printing. I run a disaster relief organization that utilizes 3d printers for education and medical items. Was really excited about this item cause of its size and seemingly solid construction. However, I regret this purchase now. The printer automatically stops after 10 mins of use. The machine also goes crazy sometimes when you pause or hit home, which lead to the print nozzle damaging the print bed. All in all, I am severely disappointed.
[EX A]:
negative
