    • Good price
Great tool gets the job done !

    • No more fishing the drain plug out of the bottom of the drain pan
If you change your own oil, this will make it a lot easier. The sockets are well made and fit a standard 3/8 drive as well as the proprietary gear wrench ratchet which may allow the use of the sockets in some situations. After loosening the drain plug the knurled collar makes it easy to remove by hand even with rubber gloves and the strong magnet keeps the plug from falling into the mess of used oil. The gasket may not be as well behaved, and there is still a chance some oil will run down your arm to the elbow, but those things can occur in any case. The rounded spline that fits into the ratchet is a good grip point after the plug is about half way loose; with fingers below the collar some of the initial oil surge will be deflected by the collar. ... show more

    • Gearwrench Drain plug socket set.
Nice storage case. Ratchet ok, magnetic sockets with knurlde ring would be perfect if they little deeper, afraid they may round off a tight drain plug. Use regular socket break drain plug loose. Then use magnetic socket to spin out drain plug.

This GearWrench Oil Drain Plug Socket 7 Piece set is outstanding. I just love it! It is so very easy to use and has performed flawlessly for me. I use this product for every oil change I conduct whether for my own vehicles or on friends vehicles. I have never rounded another oil drain plug again using this product. I highly recommend this product for any of your do-it-yourselfers or even those that own or work in their auto shop. It is very durable and the magnetic sockets make getting the drain plugs our so much easier. ... show more

    • Very nice set for any DIY oil changes!
Great little wrench set. Not craftsman, but a good sturdy product. Very strong magnet which will have no problem holding onto the oil plug. Good handle length makes it easy to maneuver underneath the car, but personally prefer it to be a bit longer for better torque, which would make it easier to loosen bolts. ... show more

    • Good quality, low use potential
(review revised 10/28/09) The Gear Wrench 7 Piece Magnetic Oil Drain Plug Set is a high quality ratchet set with nice sockets that have finger grips for those hand adjustments. While is labled for drain plug usage, one would probably find several other applications. Unfortunately for me, it will be a low-use item. I didn't note that the version I purchased was metric. In fact, at the time it was NOT noted by the seller (not Amazon). Since my 40-year-old truck most definitely uses a standard sized plug, I won't be using it there. And right now, it's cheaper for me to take my Honda somewhere than to do it myself. Additionally, even with the low-profile ratchet and sockets, you still need some decent clearance to get this where you need it. I ended up buying a flex-end wratcheting wrench in the size I needed to slip over the drain plug, which works better for me. If you are a casual home mechanic that regularly works on newer cars or imports that use metric sized drain plugs, then this would probably be a good purchase. The nicely milled and cnc'd color-coded sockets are easy to identify, and have a good weight and quality to them. And the magnetic feature is nice to keep the plug from dropping into your oil (nothing worse than fishing for a plug in hot oil)! However, if you only work on one vehicle, or if you have very little clearance to get to the plug, your money would probably be better spent on a high-quality ratcheting wrench of the size you need. ... show more
