It worked for one hand. And in the end, it never worked again. It made the five fingers shoulder perfectly and quickly. Money wasted.

Very good little oven, I have it for a short time of course but it does its job perfectly (and very convenient for traveling due to its size)

Quite good.. it does its job perfectly fine.. I have already done my nails twice and I had no issues.. I don't have any comparisons with more expensive ones to tell you, but for personal use, it's perfect..
