I bought the Axxium soak off colour gel after attending one of opi's awareness days, initially just for curiosity, and must say, it's more than exceeded any expectations. (And I am hard to please).
I applied sets on two friends to assess it's wearability, and one month later it's still there on both of them, obviously lots of new nail growth, but still intact, and shiney.
At the end of march there are new colours coming out too....(and it really is dead simple to apply,and soaks off in less than 10 minutes with the foil method and heated mitts).
I'm charging £25.00 per set, and have three bookings already. Not tried it for toes yet, but I imagine that will be very popular for summer.
