There aren't many products that I rave about, but I absolutely love my Fumoto drain valve.  I installed a F-106N on my 2008 Hyundai Sonata (with a 2.4L engine) and it's never coming off--until I sell the vehicle, that is.The quality is high.  The Fumoto drain valve incorporates stainless steel and brass.  It employs a ball valve, which is a tried-and-true bit of plumbing technology that is used in a huge variety of applications in industry and your very own home.  In short, it doesn't leak the slightest bit when the valve is closed.Installation is easy.  You do have to tighten it using an open-ended wrench, and go by feel alone regarding how tight to make it, but you can handle it.  Just don't overdo it when you tighten it. These Fumoto drain valves have recommended torque values that are typically lower than those of a standard steel drain plug, because the brass that comprises their threads is softer than steel. (The maximum recommended torque for the F-106N is 18 lb/ft.) Also, they don't recommend tightening the Fumoto valve using the hex part of the nipple.Having the Fumoto drain valve greatly eases oil changes.  Greatly?  Yes, especially if you are aware that oil drain plug crush washers ordinarily need replacement, lest leaks develop.  With the Fumoto drain valve, you won't have to worry about overtightening, worn washers, getting oil all over your hand and arm (and floor...).  And of course, you don't even need a wrench to change the oil.  With the N-type Fumoto drain valve, you don't have to use a hose, but you can use one to prevent a mess if wind or other issues require it.I occasionally have my used oil analyzed, and when I do, the Fumoto drain valve is a great way to get a few ounces of oil out without a hassle or mess.  And it's easier (for me at least) to get an uncontaminated sample using a Fumoto drain valve than using an evacuator.I've seen some people complain that a Fumoto drain valve increases the risk of vandalism.  Seriously?  I very much doubt there has ever been a person who was intent on doing harm to a vehicle who squeezed underneath it hoping to find a Fumoto drain valve, didn't find one, and then walked away in defeat.  All it takes to remove any drain valve is an adjustable wrench.  The same wrench that can smash your body work and windows in.Before ordering a nipple-type Fumoto drain valve, I'd urge you to check to make sure you have adequate clearance underneath the oil pan.  The nipple on N-type Fumoto drain valves only adds 5/8" to the regular Fumoto drain valves, but if you have a vehicle with little clearance to begin with, it could make a difference.If you have a Fumoto drain valve installed and you ever let anyone else change the oil on your behalf, make sure to tell them about the Fumoto drain valve, and explain that it has a lever that needs to be lifted and turned.  I have seen reports of people who brought their vehicles into a shop only to have the Fumoto drain valve removed completely.  If that happens, you can't be sure that they won't overtighten it, use the wrong washer with it, or even if they'll reinstall it at all.The other piece of advice I have to offer is that I use a 1/2" vacuum cap to protect the nipple of my Fumoto drain valve from road debris and dirt (your local auto parts store has these vacuum caps; or you can order them here).  I don't feel that this is necessary, but it's probably a good idea, especially if you ever have your oil analyzed.
