Be careful opening and using the system. Other wise love the product
I tried this system and was pleased with how easy it is to use and also love the color.  My draw back is while using the product too much of the finish gel came out and it spilled every where.  Once I was done using it, I closed it and it glued itself shut.  I am currently looking for a way to reopen the bottle but chances are there is no other way other than to replace it with a new one.  If I figure out a way I will update this post.  Seller suggested putting the bottle in hot water... with some muscle I was able to open it the bottle and clean the top with acetone.  They also suggested cleaning around the rim after each use. Hopefully will not have this problem again.
