Bests & Worsts Reviews from Amazon

I purchased this just over 3 years ago and it just started to leak from the handle when in the up (hot) position. Otherwise, it has been perfect. I'm not sure how long these types of faucets are supposed to last so I only deducted one star. I've installed this twice now (replaced the countertop) and installation was a breeze, albeit time consuming since I don't install faucets very often. UPDATE (04.16.16): I used an allen wrench to remove the handle. You'll need a mirror to get an idea of the angle to place the allen wrench at. Use the long end. The short end doesn't make it. It's tricky, the angle of the allen wrench is not what you would think it is intuitively. Once the handle was off, I removed the cap holding the cartridge. I inspected the cartridge but it looked in really good shape with no wear to be seen. I applied silicone grease to the three o-rings and the entire outside rim. I reinstalled the cartridge, and put the cap back on. I tightened it with an adjustable wrench, but not too tight. Put the handle back on and no more leak. I'll report back if it leaks again, trust me. UPDATE (10.30.19): This has leaked every 6 months for a number of years now. Sorry for not updating sooner. Silicone grease always fixes the issue ... for 6 months. But you have to take the cartridge out. I have a "kit" that I put together myself at this point. The "fix" now takes me 20 minutes from the 3 hours it took me the first time. Annoying, but not enough to spend on another faucet.
