Wrong product for me

I was hoping that I could use the adapter on a 3 ring front chainring from a mountain bike, but the holes are different. It turns out (that I didn't read) that it is for use with the chainrings from SBP
quality fix if you're using a wide crank bottom bracket

Seems sturdy enough, has two points to attach to shaft for a solid connection. Good snug fit and sprocket aligned perfectly. Would have been nice if either the adapter or the sprocket came with bolts but luckily i had some extra laying around.

well made and light, sprocket fits nice and tight. note: two set screws , one for the pin and one for the spindel
