a nail techs view i really like this gel [SEP] the builder nail gels kit in clear pink is medium to semi thin especially if it is used in warm temperatures it is nothing like polygel though it includes a slip solution the clear is really clear and the pink is nice also though i do not use colors a lot this applies so easily for me cures as expected and looks great i am even able to build an apexthe brush and other accessories are sub par like what most inexpensive sets have they will do well for a newbie until they figure out if they like the process then they can replace them with better quality itemsthe slip solution is confusing to be in a builder gel kit though i find it great for wiping the sticky layer off the nails after application it can also be used to clean the brush handle and any other sticky placesi am more than happy with the quality viscosity and end results i achieve with this builder gel you also get a large amount of product to work with it will last me a while i love working with it and would definitely recommend it
