These are awesome. Whilst the mechanics of installation are easy, the actual lifting and putting into place was certainly a two-person job - the unit is quite heavy, and it's too much to try and hold the unit in place with one hand whilst screwing in the holding screws! Please excuse the the rest of the kitchen....we're having a new kitchen installed and re-decorating, but wanted to have the lights installed first, so that we could be clear where the island will go.
