Hi there
I have Syster polish, i am not a professional yet and I'm just practicing uv gel nails at home. I get my cnd shellac polishes in the mail very soon (yay!) and am starting my nail technician course in 6 weeks at the Australian Nail Academy.
(I'm so excited!)
Yes the Syster uv polish is actually ok, i applied it to mums nails 2 weeks ago and it is still perfect and intact.
I think coz it's a knock off of Gelish I wouldn't wanna look like a Shyster (haha) by using it in a professional setting.
Using it at home is perfect if you're practicing like me
It has good staying power
