I've used these bolts on several climbs on some easier walls that I'm developing. I admit, I went with them mainly because they were the cheapest ones I could find, but after using them, I must say that they've done the job quite nicely. I will agree with both of the previous reviewers in that the bolt hole is close to the 'biner hole which will cause some difficulty if you use bulkier bolts or if you're on an overhang, but if you're like me and are just looking for a simple bolt for a straight forward climb, this one's not a bad choice.
