"As tile spacers go, these are fine. They do the job, and come in a monster bag that covers a vast area. The bag (at least the one I got) wasn't re-sealable as described, but that's hardly a problem. Oh, and they description says they're blue - though perhaps that's spposed to be the bag they're in. That wasn't blue either though... The only minor niggle is that they're rather tough - if you want to break one leg off for edges or odd situations, they're beyond my fairly strong fingers - I had to get the wire cutters out. Apart from that - great - and cheap.
I've given it reliability of 1 star because as long as Screwfix keep insisting we rate things on something long-term that we can't yet judge, I'll keep inventing silly scores."
