I wanted to use this for my impact sockets, but several would not fit. This is a great product though!I bought this full set of sockets and holders for one reason. I wanted a complete set of SAE and metric sockets that had a socket holder that was easy to read and identify the socket I needed. This set fit that bill. Previously I had various socket sets that never covered all the sockets I needed. I would get socket holders to put them in and would never have all the sockets for the holder. I like to be organized and don't like having missing pieces in my tool box. So I bit the bullet and bought this set. I just got them so I haven't had a chance to use them much. So far I like them. There is one small issue I have with them. All of the sockets fit perfectly in the socket holders except one. The SAE 5/8 long socket does not fit in the holder. The hole is too small. I don't know if it's just my socket holder, but you would think there would be a quality control check to make sure all the sockets fit. That is my only complaint about this set. If you want a complete socket set with holders this is a great one to get.Definitely worth the purchase to keep things organized.If you want to organize your box, free up space by using the magnetic strip on the side of the tool box, this item is for you. Actually, I stuck mine on the inner hood of the tool box. I now keep my sockets organized and easy to find. It's amazing and it only took me decades to discover this. Ha ha.Good quality Thank youMore than half of the full set for all SAE and Metric were broken. The packaging of the box sent was not damaged at all, but as you can see in the pictures, there was little to no quality control before sending out the product. The magnetic bases were over torqued when drilled into the plastic socket holsters of the item. Some of the plastic holster portions are just cracked/split along the sides as well.I will be happy to change this review if the seller contacts me back to replace the items. These are expensive and so far, very poor quality.EDIT: the seller did replace the items at no charge. However, the plastic to magnetic backing is still flimsy. Knowing how expensive these are, I would get the more expensive brand in the future with sturdier plastic and connectionsThe half inch sockets don’t stay in the slots. Magnet is weak. The other sizes work. Not worth the money.I feel the holes for the sockets are way too large. Half inch drive socket could’ve been laid out much better.
