really as described

I'm since 1996 the nails and wanted to something new.
The gel has a good viscosity and can be applied just fine. I think 1 repeated application is sufficient. After curing, I have tested the thermal effect time with hot and cold water, it really works as advertised and can be seen clearly in heat and light gray dark black when it is cold! In addition, a good price for this quality! From me, there's a strong buy recommendation!
