Hi, I use ACG and Rock Hard. The gel,polish range is very good, fantastic range of colours, last the 2-3 weeks. They are quite thin in the consistency though, but have noticed that recently the newer ones are coming more thick.
Rock Hard gel is very strong. I find it is better to sculpt with than tip. The white pot gel is rubbish, colour is very light even greyish. It's better to buy the white paint if you are to do a French finish. Look on YouTube, they have some great videos on it. The clear builder gel is cyst all clear too. But as its file off only, I do find this puts some clients off wearing it, although I wear it a lot.x
