*by L***T on 21 June 2024*

This product arrived early and I am really pleased with the quality of these airbags. It has made the ride in my motorhome much more comfortable. The only downside was that coming from abroad the fitting had to be altered to fit metric tools but the garage who fitted them said this was no problem and that they were a lot more robust than the last ones provided and fitted by a English company, and a lot cheaper too.
