Great when it works correctly.
I love it when it works. However, I had a very hard time at first getting it to charge, then it completely stopped working. Turns out there was a problem with one of the gold pins. I had to continually open it up and adjust it, which was very hard even with tweezers. Then I discovered there was a piece of plastic impeding the pin and pushing it up. Once I fixed that, it is working better. Also, although I got an extra face mask, I did not get an extra breading “tube” which I really like to use, and its would be handier to have that than the extra mask. I do use it regularly; sometimes I have to press the button two or three times to engage it, despite it being fully charged. It has gotten better as I’ve worked out the bugs. Could be a great product with a more careful manufacturer.
