The idea here is good - a reusable metal holder with easily replaced pads. In practice, Decathlon don't sell the replacement pads, so you'll be looking for those elsewhere.
These we're great, gone through... MANY swapped pads for these. It seems decathlon have stopped stocking the replacement pads though, can never seem to find them in stock. Either buy a bunch with the cartridges as you'll then get your moneys worth or look at alternatives.
They do what they say on tin
Not that I know of
Started using these instead of more expensive ones. These do the job perfectly. Perhaps are a but thicker than normal so will need to adjust bike a little. However, à Los bought the replacement pads and will be sticking to this brand.
Universal fit Good quality. Replaceable pads
