Wow, this is an extremely nice set of metric wrenches!!! I'm REALLY impressed with these, and love working with em! I've already been using the SAE sister set of these wrenches and they've really impressed me, both with there quality and there toughness. This set is the same, very tough, and very high quality made wrenches, professional quality! All are ratcheting box ends (reversible with a push of a button), and instead of the cheaper point style box end, these are the spline box end, which grabs the flat side of the nut or bolt, so no problems with a nut or bolt thats previously been rounded by someone else, if it still has the flat surface intact, these will work great for you! The finish is beautiful, with a mirror polish shine, also they're strong as a mule, as I've already put my SAE set through some tough tests, and they all passed with zero problems at all. All of the interior gears and teeth are hardened steel, and all are 90 tooth geared, so you need only a little room to make progress, and I really enjoy the length of these, that allows me to use plenty of force with those rusted or stubborn nuts that don't want to come off. They do with these wrenches! The 90 tooth gearing also makes for very smooth ratcheting, these are just a pleasure to use, I love working with them. I think anybody who has an appreciation of fine tools, would love both this set and the SAE set of double box end, spline drive ratcheting (and reversible) wrenches. This is a really good price for a professional set like this, and I very highly recommend these to all who need them!

Amazing Wrenches. Highly recommend buying these. I have used them now for a couple months and put them through hard daily use. When you need them they come in handy. I was worried about buying them with there being some reviews saying that the warranty was difficult but I broke one and it was super easy talking to the seller and within 2 days I had a new one shipped to my door.

This is a good product and very handy for those hard to reach area on my car. I have used this several times and i honestly can't complain about how useful they are when i needed something long and flat for those hard to reach area underneath the hood or around the engine bay area in my Toyota Solara. I just recently replaced a Rack and Pinon on my 2006 Toyota Solara SE Sport 2.4L and this ratchet (especially the 17/19mm) saved me a lot of time when it came to tightening the two big bolts holding the rack and pinion in place. I think you know what i mean if you have replaced a rack and pinion before on a Toyota Solara. This area is to tight and you need something long and flat to get to the bolt otherwise you will need to lower the frame and the stabilizer bar to get to these bolts. As for the customer service experience i had, i will rate the seller 5 stars! Excellent customer service! I was replacing my driver side knuckle/spindle the other day when the little locking pin on the side of the 17mm ratchet just fell off. I tried to put the pin back in place but i wasn't successful and the ratchet won't lock and just kept rotating. I knew it was too late for me to return the item because i had already missed the return window set by Amazon for this item. However, i decided to send the seller an email and explain to them what had happened. I was delighted a few days later when i received a FedEx package containing a brand new 17/19mm Spline Reversible Ratcheting Wrench. I am very happy that they did because this is the one i use the most. Thank you for taking care of your customers. It means a lot to me!

As an auto tech I have had these for over a year but only used them a few times when I really need to get deep into a dash panel, around a steering shaft, or down in the middle of an engine compartment, or get to an exhaust nut- ie, the 5.3 Chevy exhaust manifold nut that I have no other tool for because the frame and wire harness is in the way. If you have replaced the cylinder heads on these engines you know the challenge. All the engines I have worked on so far have been fairly new so the nut wasn't completely rusted out but still I was very impressed that it tool off the nut without a problem. As Bob mentioned in another review- the wrenches will stick to the nut or bolt when they are new so they can be a bit difficult to get off the fastener after loosening. I use these wrenches very rarely but for the cost they are completely worth it and a time and knuckle saver for those tight spots where nothing else works. I think they will last a lifetime for me. I imagine they would wear out if used every day but most gear style and flex head wrenches will.

My buddy moved back into town and had a set of these. And I used them a couple times and had to have a set. A flexible ratcheting double box end wrench. You'd be surprised at how well these work and how many places you can use them. I am thoroughly happy with these. Just make sure if someone else uses them they know righty tighty, lefty loosey. As they pinched a bearing in one of mine and now the bearing is deformed so it catches and locks up every so often. So I guess that would be my only draw back is the material used for bearings could be of a stronger metal. All in all. I cant belive it had never seen them before or used one. Absolutely love them.

I've used these swiveling ratchet wrench a few times now, and they do come in handy. I like the length. The racheting mechanism is a little stiff, so once one breaks the nut / bolt free, you might have to help it along. I had to put my other hand on the top part of the bolt to keep the mechanism from just rotating the bolt back and forth. And the little button / switch to make the wrench switch the operation from loosen to tighten wasn't very sure fire. I had to press that switch rather firmly to get the ratchet out of the free wheeling mode that it ended up in when I first tried to change it from loosen to tighten. I have these soaking in a light oil now to see if that helps. I'm starting with 4 stars here and we'll see how these work out. Not bad for the money at this point.
