I think that’s a pretty good review. 
If you’re looking for things to add, a wrist measurement would be useful so people can get a tape measure out at home and judge how loose/tight the item might be from that information. Also if you find yourself typing ‘I didn’t check so and so’ then I would pause and go and check it if you can, rather than guess.
Different items have slightly different review techniques, and I don’t tend to do bondage items that much so I’m not the expert 
, but looking at the other reviews for similar items can often give me inspiration for extra details to include in my own reviews.
There’s also the Review Hall of Fame with all the winners and runners-up of the old Review of the Month competition in that can be good to crib ideas from.
