The part worked

Received product on time as promised and the package in good condition. Installation was easy and with no issue. When installing the serpentine belt make sure tensioner bolt is loose. Once the belt is on than tighten the bolt. Do not over torque the bolt or you will experience broken bolt down the road. As on quality and durability, only time will tell. I will repost this review when quality issue arrived.

One of the comments I had read in a customer review mentioned that the main mounting bolt ended up breaking after installation. I was concerned, but upon examination saw that the bolt is a grade 10. I made sure to install the new bolt using Honda torque specs. A few months after driving with the new tensioner, the mounting bolt in our Pilot also broke--stranding my wife without the serpentine belt--and leaving a broken stud in the engine that took quite an effort to extract. I was stymied as to why a grade 10 bolt would break, as it certainly was not over tightened since I had used a torque wrench to install it. Luckily, I had not thrown away the original tensioner and I was able to carefully compare it with the replacement. What I found--and what the photos clearly show--is that the original tensioner in the photo on the right has a machined and perfectly flat surface where the tensioner contacts the engine. The replacement tensioner pictured in the photo on the left does not have as precise a surface and actually has rounded edges almost like a washer which allows for a constant, albeit small bit of torque to be appleid to the bolt as the engine is running which over time will fatigue the metal and eventually break. I was lured into purchasing this tensioner by the low price compared to what OEM costs, and in this case cheaper price resulted in a cheaper part. I recommend finding a tensioner with a machined contact surface like OEM, or purchase one from a salvage yard. I have been quoted a price of $35 for a tensioner from a local used auto parts yard. Save yourself the trouble of drilling out a broken stud with a right angle drill and then using an EZ-out to extract it. What an ordeal!

works well

Very good product

Stopped the awful belt noise I had, so I'd say it works. The only nitpick I have with this assembly is that the lower pully (non-tensioned one) has a much higher rolling resistance than the OEM one so may wear out sooner, but for $30 (vs >$100 for OEM) it's worth it though.

seems very well built.

IT LASTED ONE WEEK. Bolt snapped while driving. This time it broke off inside the engine, 1270 dollar repair at the shop. THANKS A LOT. The people who designed these aftermarket hunks of trash belong in prison. Somebody is going to get killed when their power steering goes out in traffic and cause a huge wreck. I'm very lucky that out of all three times these garbage things have broken on me, there weren't any cars around me.On my pictures, you can see where the bolt snapped clean off, and see that it's garbage pot metal. Something the manufacturer could fix for pennies per unit. You can also see that it had cracked at some point but not sheered, thus the belt rubbing against the tensioner and wearing through the metal enough to spring a leak. Hardened steel shouldn't be worn by a mostly rubber belt.I've been through THREE of these from supposedly different manufacturers yet they all look and feel identical.This one has a bolt which is 18.5mm. A socket that doesn't exist, therefore you get a terrible fit and it spins when you apply torque to slip the belt on. That's using the actual tool from Honda made for this single purpose. It's made out of the softest metal possible. It is not hardened steel. After rounding it, the only other way to get a belt on is via prybar.Even the mechanic shop put a new "oem equivalent" and I inspected after they "fixed it" and found it also was rounded. They stated that theirs had a return rate of 4% which is "really good"I'd say if 4 people in 100 die using your product, athat's pretty trash.The last one didn't last 2k miles without exploding and destroyed my power steering.STAY AWAY FROM THIS. Buy actual OEM from HONDA and nothing else here on Amazon because 100% of them suck and will fail on you. False advertising "strong and durable" not even remotely.
