This is a peculiar product. It represents the first time I have ever seen 12pt. 3/8" AND 12pt. 1/4" drive sockets sold together in a small set. There doesn't seem to be any advantage to this setup since the 1/4" drive sockets are largely - but not entirely - the same size as the 3/8" sockets. Based on experience, I would have expected to see the smaller sockets in 6pt. and the larger ones in 12pt. (In fact, if you look at the product picture, that is exactly what you do see - which makes me suspect that the end-product wasn't the original intent.) The parts list is available as a .pdf in the description. So, I already knew about this peculiarity before buying. And, since the 'blowout' price was excellent, I bought it anyway. I purchased the set for indoor jobs and do not recommend using for engine work or on rusty bolts since using 12pt. sockets in anything less than 1/2" drive increases the odds of bolt stripping. Everything has performed well to date, and I haven't had any part failures. The 45T ratchet is a little heavy but works smooth enough and doesn't bind. The 3" extender and 1/4" adapter were nice additions as well.
The product was functional and of good quality. Dealing with Sears on the other hand was a nightmare. Deceptive advertising. Numerous advertised items not in stock. Sent me to a store that was out of business for pickup. Customer Service Representatives rude and not helpful. No wonder bankruptcy is their path. What happened to this once fine company?
