Not sure if I would use this again

I bought this product to remove my Shellac manicure at home. After roughing up the surface of the nail I used the foam pads soaked in acetone, placed the re-useable cap on the finger tip and waited. After waiting 10 min, I removed the cap and foam, the polish started to dissolve, only part of it so I repeated the process and after 2 trys the Shellac came off , but that was only one hand. So in all it took about 50 min to remove the Shellac from booth hands. Would do this again if I didn't have the time to go to a salon to remove my polish, and maybe trying with cotton next time instead of the foam pads.
