Good trolley. ......... for 12 months

I bought my Prorider electric golf trolley in June 2013. All went well untill june 2014 when the controller failed just in warranty and was replaced. Three weeks out of warranty the battery failed in spite of beiing charged after each use about once or twice a week. I know batteries wear out but not in 12 months (3 months of that due to winter weather it was not used), on my Powakaddy I have had batteries last for 4 years!. I complained to Prorider who sent me a sheet on battery maintenence which clearly indicates that you should work on 18 to 24 months for battery life. I explained that mine lasted only 12 months but they refused to replace it as it was just out of warranty which I find very harsh.
Clearly these trollies (and batteries) are of dubious quality sold by a company that strictly operates warranty dates without a modicum of flexibility.
I will not be purchasing again and will revert to a trolley that has a reputation for quality as it seems you only get what you pay for.
