I have only given this four stars as I think it needs another eyelet for a bungee strap in the middle. I have had to put a large stap from one side over the top to the other as the middle flaps in the Cornish wind. Other than that it is a super quality product as I have plenty of weather here on the North Cornwall Coast and it does the job well.
Good sturdy cover and looks the business - would have given it 5 stars bar for the fact that really it could do with extra bungee holes in the middle to anchor it down to stop it flapping. (especially for the clear part of the cover)
Overall, pleased with it.
