Works, but manufacture issue

Work for what I needed but some very thin places, where silicone is actually falling apart already and only used twice

Cheap price, cheap quality....but works as it's supposed to.

Ok, I ordered two.  One arrived and works great.  One had two short circuits in the barrel connectors.  After taking them apart (These are the type where the cover and strain relief screw into the connector) I found too much heat was applied while soldering and the connectors shorted out.

I was able to repair them by cutting the leads and doing a little surgery with new connectors.  Still the issue I found took less than a minute with a continuity tester which is basic quality control.  This should have been caught.

I got two of these. One had a problem with the middle section not screwing all the way in, leaving visible metal threading. The female threaded end was 1.1cm too long it seemed. I used a rachet-style tube cutter to rip off the excess size (using pulsing movements rather than slow 360 movements, to avoid the blade just following the threading). Then I used bolt cutters to remove the excess section of metal threading (to get it off the wiring), and then screwed it back on. Looks how I want it to now. I've seen other complains about this, so they could use some QA here.

It works with my 3-way A-type dimmable LED light bulbs (though not with other A-type dimmable LED light bulbs I have). Be sure to look for the term "3-Way dimmable" specifically.

The price point is pretty hard to beat though.

does the job well, the wheel is a little off center so better quality control should fix it, but alas it still worked

Ordered 2;  One worked, the manufacturing tolerances on the other were well out of acceptible norms on the other based solely on visual inspection  (the usb connections).
Can get the 2nd to work by manually applying pressure on the the usb connector on the cable to establish electrical connection (but who would want to).

works fine, but it is the second one; first one arrive with seams not bonded, so had three big holes

Generally works as advertised, with two minor issues:
First, the response time is slightly slow, on the order of a second or two -- so when you're waiting on the hot water to get hot, it'll overshoot slightly before settling back to the set temperature level.  Not a huge issue, and I believe most thermostatic valves work on the same principle so you probably can't expect much more.

Second, on the unit I received, I had issues with the cold water flow.  Finally figured out that it may have been a manufacturing flaw or something -- there's a little check valve on the cold water side, and it was actually moving around slightly and would block the hole in the casting that's used for the cold water through port.  I suffered very low cold water flow for a while as a result -- once I figured out why I removed the little check valve piece entirely and it works (though theoretically this can cause the hot water to backflow into the cold).

Otherwise, this is a well built unit and does its job, keeping me from burning my hands in the kitchen sink!

I am happy with the product, but there are some real problems at their factory.  The product arrived with some minor chipping on one corner that could have happened during shipping.  No biggie.  It also arrived with one of the two drawer-fronts partially knocked off, and the rear wall of one of the drawers completely broken off in two places.  Further, the center guide rail for one of the drawers was loose and fell off as I removed the drawer to try and fix it.  That rail had mismatched screws, one not even long enough to bite into the wood.  Since the drawer was fully inserted and protected by the drawer case, none of this damage could have happened during shipping.  I can't even figure out how this damage could have happened during manufacture.  And the wrong screws?  Replacing the screws, clamping and gluing the drawer front, and gluing the pieces of the rear drawer wall together was easy enough, but not work one expects to have to do.  Also, you need a power screwdriver (or alternatively a drill) to put in the 24 screws, as they are self tapping wood screws with no holes drilled in the wood.  Again, not much of a problem but it would surprise someone who got this and thought, per the instructions, they just needed a screwdriver.  At 130 pounds, flipping the unit over during assembly may need a second person, depending on your strength.  All in all, this was not easy "Ikea" type assembly.  The unit itself however, is quite solid, seems
well engineered, and is attractive.  So I compromised and gave it three stars.  I am happy with it, but buyer beware.

works ok but had to do minor repairs as it was assebled

This adapter works well in aluminum housings with liquid pipe sealant.  Residual machining waste was adhered to the fitting, requiring solvent and a scraper to remove, hence the 4 stars.

I like these brushes and buy them often. However, when there is a manufacturer problem with them -I have 2 with manufacturing issues- it is a challenge to return the merchandise! Otherwise they do a pretty good job.

works as advertised; factory fit and finish.

They get the job done, but the quality of manufacturing is sub-par.  I noticed that both of my adapters were tilted, sort of like the Leaning Tower of Pisa, so I tried pulling on one to straighten it out but instead the whole bottom fitting just popped right out and I had a disassembled adapter in my hand!  I tried to put it back together, but I couldn't get the press fit bottom to sit tightly enough in the body to stay.  I left the other one alone and it works fine, and you can't notice the tilt when it's plugged in.

I probably wouldn't buy these again, but I will use the one thats still in one piece until it breaks or I lose it.

Worked on my 2002 F350 with a 7.3 liter diesel for about three months, then I started having problems in the ICP sensor circuit. It took me several more months and a shop with a breakout box to figure out that one of the connections in the plug was not crimped correctly and was not allowing the sensor system to function correctly. This issue forces me to question the quality control in producing this item.  I thought the wire in the pigtail was very light compared to the original wire.

Quick ship, seems to work O K ...New unit, might last, might not,

It works, but not perfectly.  It actually stuck out too far on my head unit.  I probably would see what else is out there before buying this one.  Heck they didn't even trim the plastic from the factory.  I had to do it with an exacto knife when I got.  Poor manufacturing for sure.
