I had the opportunity to review this as part of the Amazon Vine programme :)
These pair of ratchet straps, do seem a bit better than usual run-of-the-mill one's you'd find kicking about a DIY shop (the cheaper ones, anyway).
In the box you get two 4m ratchet straps, each strap claims to have a 500kg load capacity (I haven't tested at anywhere near this weight though), and they also have 25mm polyester webbing (good but not the most eco-friendly) with rubber-coated “S-hooks” so you do get a secure grip without scratching surfaces. They are fully EN12195-2 compliant (which means they’re safe for domestic and vehicle use) and come with a lightweight ratchet and a zipped carry pouch for easier storage as well.
The straps can be used for stuff like roof storage, or vehicle loads etc., and are suitable for anyone needing something that's reliable but also compact as a tie-down solution. The quality of these genuinely seem quite good, and to be fair, I've had no major issues with them at all (I mean, so far, anyway).
Ultimately, though, they honestly do seem pretty good. They are not only pretty functional but practical as well, and in my opinion, they are good value for money if you're in the market for something like this!
