"Was easy to install and seems to be doing its job. I used to fix into brick and it's holding fast and no signs of blowing the brick (because it's a big fixing that goes fairly deep). I would say that when I bought the fixing I chose the M10 thinking that the overall diameter would be 10mm but that wasn't the case. The bolt is 10mm but the anchor itself is 16mm, so it's pretty big. Would of been useful to have this info on the website because I didn't need a fixing this big. I would of gone for the M6 which was cheaper and I already had a drill bit that would fit this"
