Did not work for my OHH55

Did not work for me. It fit just fine, starts right up after priming, but dies after several seconds. Just does not stay running no matter what adjustments I did.

Nothing wrong with quality but this just did not work on my 2007 Honda Shadow 600. It has four plugs for two cylinders. Two of the plugs are relatively easy but two are set at a angle center of cylinders. The length is fine but even with the thin wall design the socket can't hit the angle to get over the plugs. I even ground off to taper some of the socket thinking this might help. Some have said that buying a 12 pt deep well Craftsmen socket works and I went for ordering a Honda socket that was not in my tool kit. Really the bummer here is that Honda developed a head that if it had only added 2 or 3mm more in diameter a person could get to these plugs much easier.

Model indicator said it would work on my model series. Had to ship it back as it was wrong one.

The one that came with my mixer had an ear fall off. This one was fine but didn't fit my unit. Turns out they have many versions of the 5 qt mixer. All with arcane stock numbers that are indecipherable.

Does not fit my unit. Advertising is not clear or complete for all models.

Did not work on my Kenwood. When I plugged it in, it made the unit broadcast instead of listen only.

I bought this to use with OpenHAB.  I mean, a CT100 is a CT100 right?  Nope!  This had an incompatible device ID (6501:000b).  Even after having the Device ID included in the OH2 device database entry for the CT100, this thermostat would not report any data.  I gave up and bought the white version which IS compatible and works great.

I'm sure it works okay as a regular thermostat though but never got that far.

This was recommended by Amazon when I put the H1 Zoom in my cart. I was lazy and assumed it worked with it. It only works with my android phone so I will keep it. I had to order another lav mic that was known to work with the H1 Zoom. Oh well that was my mistake.

Included shaft adapters didn't fit my DT750 motors, had to order additional adapters separately. Documentation incorrect - doc actually indicates that the adapters should work.

If you are trying to program the Clicker KLIK1U remote to an OVERHEAD DOOR Model 551.....Stop trying.  It won't work.  The packaging states that it "works with ALL major brands" including Overhead Door.  After two frustrating hours, and going through a miserable technical assistance phone call, the rep searched the internet to find out that this unit is not compatible with model 551.  I'm hoping that you save yourself the same negative experience.  The packaging is misleading, the instructions are poor, and the customer service is terrible.  The product might be great for other garage door makes and models.  But not all, as I just found out.

UPDATE:  I purchased the Keystone Model 0220-KA, for 390 MHz signal, set the dip switches, and it worked great.  Hope this helps

I ordered this for a Toshiba c55t variant that was listed as one of the models this would fit. It was about 1/2" short and will not work. However, the seller did take care of my issue. They told me the manufacturer makes two models of this jack and they cannot determine which one it is while they ship.

I am bummed since this doesn't fit my keyboard even though it is listed in the description.  I have a E5550 and the arrows don't align with the arrow buttons and there is no page up page down button.  Also the numeric keys don't align.  I don't use the track button in the center of the keyboard so this isn't a big deal for me but it would be impossible to use it.

This does not work for the Lorex Lh070 series.  Can't really attest to the quality of it as a product since I can't use it. Quick shipping though.
