Bimble were friendly and helpful when I initially contacted them and despatched goods the same day. They should have been delivered next day but UK Mail fracked up and I didn't get it until 2 days later. Bimble were also helpful with a technical query I subsequently called them about.
I have used Bumble solar for several projects now and always find them prompt, matter-of-fact and easy to deal with. I find their directness refreshing and they always deliver on time. It has to be five stars.
