I fitted both of the extenders making sure both the mirror nuts were tight and the bolt into the bike was tight. I went on a ride and within 20 minutes one of the brackets moved - the bolt wa still pretty tight even though the bracket could be moved. They should be supplied with some sort of washer to prevent this. The space the bolt goes into is too small that any washer you’re likely to buy will not fit.
Disappointed for the cost when I see cheaper ones on Amazon supplied with such washers.
The positives are that the extenders do look good and when they arrived they are well presented and packaged, so you feel like you are getting a quality product. They are also a good length so when they stay put they do what they are supposed to.
