These are a must have. I can't believe how long I went without them. In today's tight engine spaces, these will make putting bolts in or taking them out so much easier. Worth every penny. Yes, the magnets are very strong. You might find the socket staying on the bolt as you pull the wrench away, but it is worth it. I would like to see them in a more compact case. The case they came in is rather wasteful with space. It might be best to plan on putting them on a socket tree.
