yes.
Fitted a couple ,last one was 4 aculmalators and a charger pump unit, all very good ,slight problem that they sent me wrong size fittings pack but phone call and they were delivered correct the next day.
Both situations ive always added a charger pump due to extremly low presure (both on hill fed by water tower)so dont know if there claims are as good as they say with just acumaltors as ive never had a decent main to try it with.
