Install was OK, although they need encouragement to give me a a date. Since the install service has been appalling bad, the unit went wrong so I went to the website which only has a link to an email address. I emailed them three times over a few weeks nothing at all no response, I found a number and called them, one of their sub contractors came found that the install (also a sub contractor of BP Chargmaster) had installed it incorrectly and burnt out the breaker, they didn't have a new one and could not get one. after a few weeks they never came back to me, I had the breaker replaced now unit works on 16 amps only . So calling them again. Avoid if at all possible.
