I change mine when I need to.When I first started doing nails I got through a few as I used to try and skimp on monomer to clean the brush and used the old leftovers.Biiiiggg mistake,I found the expensive way.Now I use fresh monomer to clean and wrap in tissue,store flat in my nail box and perfectio,as long as its doing the job properly I'm happy.
