works well so smelly [SEP] i read the reviews and saw people said the monomer smelled but meh whatever this sort of thing usually does so no big deal right it smells a lot it made my whole home smell you can smell it when you open the zip bag containing the fully sealed bottle so really if you are sensitive to smells or live in a home with someone who is this probably is not the product for you and if you do get it ventilation is a mustyes it is hard to get the right mix if you are a beginner that is part of the skill involved not a reflection of the product it was my first time doing my own acrylic nails and i think it is easier to use than gel it is not as sticky and all over the place but yes it will take practice i did get a set of serviceable nails out of it so i am happy i will probably look for another monomer once i run out of this one as the smell is just unbearable but i like the powder powder has no smell
