I wanted a not too large mirror. This pleases me very well here in terms of size. The clamp is fixed to left on the furniture without footprints. Mobil, as operated by batteries. One can sometimes quite comfortably sitting on the couch and making the cosmetic repairs to the face. The light is bright enough for me. Simply is also the assembly. Inserted batteries, arm and mirror magnetic hold, the mirror is super move by the arm and rotatable by the magnetic attachment of the ball. An ingenious part. Do not know how I could get along without previously .;)
