Work was professionally done, however, I feel like I was duped. I had 8 potlights installed in my family room but I was not home when the work was completed. I received a call from vadym about mid way through the job asking me if I wanted I dimmer installed as well but due to the price I said no. Vadym agreed it was simple enough to do after the fact myself. About a week after the work was completed I tried several dimmer switches but none of them worked (lights flickered). It wasn't until I removed and examined a pot light from the ceiling that I realized he installed non dimmable lights. I contacted him to swap them out several times but he ignored me and then ultimately refused. Needless to say I'm very disappointed.
