These braces are good and strong. They have four clips which make it sturdy, and the clips are big and individually strong. The only problem with these braces is that the back clips have semi-sharp edges where the clip joint is, so when you sit down, they scrape against the chair upholstery or surface and can easily cause damage. Likewise, wearing a jacket scrapes and wears at the jacket and still causes some scrapes on furniture. These would be excellent if there were no sharp edges to the clips. I have worn braces before and not had this problem. As for the third party company that supplied them (ingameszone), they charged me 4.48 p&p. The braces were sent second class in a flimsy plastic like envelope that had a two inch tear in it. The braces were inside the envelope with no other packaging (no box, no inner bag, nothing). There was not even a copy of the invoice. How anyone can claim that a flimsy envelope and 2nd class post on a set of braces costs 4.48 is obviously crazy. Obviously the company drops its item price to appear higher in the listing and recoups it in profit from the p&p. So, braces good, but problems. Supplier, poor and expensive! I won't buy from them again.
