Hi, they were at the Edinburgh Beaty show, they seemed to talk a good talk, they gave me loads of free products when I bought a soak off gel. The soak off gel is great. I use it on a few friends that struggle with shellac, ie under shellac with no problems at all, but must admit I use all nsi products, and all shellac products for each system.a few friends did go on the day course and said it was good, think it cost £100ish and came with a gel kit. But must admit I've not tried all the free products they gave me. Just that soak off gel and will definite be buying that product again x
