I prefer it. It's lovely to work with.
You work dry with it and it stays exactly where you put it yet you can still work with it.
There are 2 monomers but the master monomer is the quicker of the two and similar to Nsi setting time. I had to do 3 bridesmaids with Nsi Rose blush this week after using CJP recently and I couldn't believe the difference between them.
It's also much easier to file, soak off and my clients said it feels lighter and more natural and they have little lifting or none at all.
I'm delighted with it!
