Whilst I think this item is good value, there are several problems with it.
The kit is only suitable for those awnings which incorporate a fixed plastic buckle. In order to use this feature, They are not much use for the Fiamma fixed awnings on motorhomes. I have had to purchase complete buckles, as only one half is included in the kit.
The pegs supplied will probably only be useful on a grass pitch, and so I will need to use rock pegs for most hardstanding pitches.
There is no facility other than two M8 bolts which I think attached the flexible attachment. Difficulty, therefore to make a connection to the Rock pegs. Personally, I will have no problem making them fit, but many customers will not.
Finally, I believe customers would like to see some installation instructions with the kit.
You would be better to make these issues clear on the listing.
