Patience is the key
EDIT 02/28/2019: As we all know there is no "quick" way of taking off gel nail polish. The one thing I have noticed and "do like" about this machine is you do not have to scrape or file off the left over polish. It does peel nicely. Patience is the key to success with this product. Also certain brands of polish come off easier than others.<br /><br />ORIGINAL REVIEW: If I could give 3.5 stars I would. It takes quite a bit of time to soak off the gel. It is best for me to do the foil wrap and wait 10 to 15 minutes. It would take a good 15 minutes for the peel to start w/the machine and then again you continue to put your hand in and soak. Yes, I used acetone (actually from the paint store-it's cheaper than nail polish remover w/acetone).
