I really like how sturdy these are but most of all how well they organize my sockets, I’m very happy with this product I will be buying more!!!!Gave this to our son for his birthday (he's 47). It was just what he wanted.Well,I have many different socket organizers. None are really stellar which I can't understand. Seems someone could make a rail with a strong magnet. These hold to a box lid,but won't hold the sockets in the slots if tipped at all. Still,they are substantial wight wise.I think they are going to be a good orginazation tool but I think the picture of the product is misleading. In the picture they are shiny. Seems like nitpicking i know but because of the gloss finish the product appears that it could be made from metal and painted with a high gloss paint. I couldnt find anywhere what this product was made out of where the other products that where less expensive clearly stated they where ABS. This seemed to be the brand name of the bunch so I had hoped the others where the plastic knock offs. I read the reviews and I didnt see anyone complaining about it but I did see the pictures so I knew what I was getting into which is why I still give it 4 stars overall. None the less I dont know how I feel about giving my money to a company that is intentionally misleading its customers not to mention pretty dam expensive for a few pieces of plastic with holes drilled in it and a magnet on the bottom. At the end of the day though it fills a specific need and I am going to keep them. Also there is an argument that if the metal ones existed the paint would scratch and chip.Great product, by far the best option I could find…only issue is some kid the numbers have rubbed off…maybe oil or ruff use did it. I would by them again today though. I probably will get another set in time.Very happy with this productNot a bad product.The 1/4” and 3/8” socket organizers are pretty good for me. Holds both the regular sockets as well as the deep well sockets together.The 1/2” only holds one set. Either regular or deep. Not both together.As with any organization system provisions are made for sizes not practical or necessary for some uses. I really have no need for 1/8” or 5/8” sockets in a 1/4” drive system. Same goes for a 6,7,8,9,10,11,12,13,14,15mm in a 1/2” drive system.Speaking of the 1/2” system. I incorrectly assumed that it would hold two sets each. Both regular and deep well sockets. This is not the case.I have impact sockets in both 3/8”, and 1/2”, neither system will hold a complete set. The 1/2” would hold one socket, the 3/8” system held 3 of the set.The magnet is pretty strong but will not hold all sockets if upside down. I keep my sockets in drawers, no issues their.The size markings are easy to read. One of the main reasons I bought this set.I have been using the organization system that have lots of pins. One row short, the other tall. Markings are on top of the pins. Reading the size has become difficult on my aging eyes. This new system is much easier on my eyes.This system is larger than and takes more space than the pin system.I’m not using the 1/2” systems because of that and the fact they would only hold one socket set at a time.Had I to do it over, I’d buy individual pieces for 1/4” and 3/8” sockets only.I finally know what socket I am reaching for without having to put on my reading glasses. I also discovered I have numerous duplicates, yet somehow my shallow 10mm is missing. Shocking isn't it. Now I need to purchase the fourth 10 mm shallow in my lifetime.très bien
