Review (1/5): Even at this cheap price I do not recommend it.
This was so difficult to use. I felt as though my fingers were going to break trying to change the tips on this machine. Pressing that tiny button which should release the tip DOES NOT work and it hurts your fingers. I got extremely frustrated with the item and after only being able to get the two to change out just one time, I returned it. Even at this cheap price I do not recommend it.
