Ring transformer
The first from another company did not work after one use. This one is working great.

Works as expected
I needed a "doorbell" 24v transformer to power a couple of water valves. They are inside so being waterproof was not an issue. This transformer with the mounting plate was perfect for the project. Easy to install after turning power off if you are comfortable working with electrical devices. The only thing I added to the 24v side was a fuse just in case.

Excellent product
UL listed transformed. Good quality construction. Tested with Voltmeter and it was providing an output of a consistent 27 Volts.Remember, even though the transformer is listed at 24Volts AC, when connected and not under load, the output wil be at least a couple of volts higher than specifications, in this case a constant 27 Volts.My Rig door bell pro wired works great now with an RSI signal strength jumping from an average of RSI 52 to RSI 68+

It works
Seems to work and provide the correct voltage. A little noisy until it tapped the bottom of it. My eufy hardwired doorbell camera chime works as well as the original doorbell now. The original didn't work when I installed the eufy doorbell camera, it does now after installing the transformer. Hopefully I don't have to tap it again to stop buzzing. If it didn't buzz I would have given it a 5 star.

Exactly as described
I purchased and installed the Transformer, and it works perfectly. The one I got is exactly as described and there were no problems.

Worked like a champ for my HVAC thermostat
I replaced my faulty hvac transformer with this and it worked like a champ. The photos and answered questions in the listing for wire connections were more helpful than the printed instructions. Regardless, it was straightforward and simple. A quick double check on my wiring after installing and then my HVAC was back on business in under an hour of delivery.

From what I can tell its rubbish
Rubbish. Followed wire color code as given on the sticker on the transformer to get 240 to 24v. The secondary reads 98v. The instructions with the unit doesn't even match the sticker.
