Works as advertised.
I ordered the Bolsen High Temperature Resistant Industrial Grade thermoelectric Power Generation, TEG1-199-1.4-0.5 4440mm as a replacement for the one that I accidently overheated, ( my bad), and as far as I can tell, it works just as good as the original. I have no complaints, however from now on I will be more careful.

Okay I like the price, but the picture is misleading
If you aren't expecting it to look this shape by the model number, I hope this picture shows you it looks more like a normal TEC than a TEG, also it's only going to generate about 10watts@190°C temperature difference moving ~190watts thru it. Think about that in your designs.

Misrepresented in listing.
This is not a TEG. Don’t expect high temperature power generation. Reasonable price for a TEC.

These are TEC's not TEG's.
I bought these expecting them to be TEG's. Across a large delta-T, no significant voltage was produced.

Exactly what I expected!
Well packaged. Haven’t completed the project yet, but these are just what I need.

It works I guess.......
I tested two connected in series at around 350 degrees for 90 minutes or so under certainly LESS THAN OPTIMUM conditions. I got an average of 4 volts and .2amps during that time. At one time it spiked to .9 amps for about 10 minutes. I mean - it is what it is. If your goal is to build your own TEG power generator and to charge a 12battery and run a 110v inverter then this is what I recommend. Realize that you will never be able to power your house with TEG power. In other words, it can give you some power but not a lot. But - that power never stops so long as you have a fire! First - get your TEG modules from tegmart (google them). Connect the TEGs in series. Run them through a voltage booster and max that thing out. Buy a 10amp solar MPPT charge controller (about $50) They're designed to take a DC input - weather that's from solar panels or your voltage booster, the controller doesn't care - and it will also protect your batteries from overcharging! MPPT controllers convert any voltage over 14.2v into amps to charge the battery. Also - use Lithium Ion batteries. They're expensive - but they charge 4x as fast as a lead-acid. See my video.

Worked as described
Used for my wood stove fan. Worked just like the last one

Great quality product
Really matched the item description. Was really like a product much more expensive.
