speedbox 3.0 for Brose

Product works well and was straightforward to fit. Changing from 15.5mph limit to unlimited for off road use is easy. However the 5 pin connector casing was made of a very brittle plastic and the first one broke. Quickly replaced free of charge but on fitting the replacement I noticed that the casing was slightly oversize for the motor's electrical socket and would not fully seat, hence the breakage issue. I had to remove the top 3mm of the casing to ensure electrical contact.
