Review (5/5): Fabulous Gift; from 11 years ago and still GREAT!!
Feels wonderful on my scalp, easy to clean (no bumps on the ends of the wood bristles!), and EXCELLENT quality as the brush has lasted a VERY long time. Cheaper models are out there but the TEK has been very reliable.
Sometimes, during cleaning, the bristles slide down into the flexible rubber (?) base but it's very EASY to pull them out again which straightens out the entire brush (see Francesca's review - looks like that is what happened to her brush).
