Review: Reliable Transformer- Great for Ring Pro - This is a good transformer. It comes in a brown NuTone box and has a one year warranty. There is a small instruction guide for installations (1 bell, 2 bells, etc.). The transformer wires are in a threaded cylinder shaftess than 1” long. You insert this into a punch out on your juction box so you have no exposed wires. You then connect the common, load and ground (white, black, and green) to the corresponding wires in your junction box. If you are replacing a transformer you may first need to find the transformer unless it is by your panel. They tend to be in a straight lime from your doorbell (straigh line, shortest distance between points and all), so look in the attic, crawlspace, or basement in a straight line into the house from the doorbell, and near another power source like an outlet. Mine is in my crawlspace. You may find, as I did, that my ancient transformer was over-tightened onto the junction box. I ended up pulling off the box (POWER OFF! Or at least wires capped of you are a pro). This allowed me to turn the transformer unit and easily unscrew it. My only installation issue: this unit was slightly deeper than my junction box, and once I inserted it into the punch out hole it rested on the joist before the junction box. I just added some wood behind the junction box so both transformer and box are secure/nailed in to the joist. Installation itself is like 5-10 minutes. I spent more time finding my transformer and fussing with the old one’s “frozen” mount than I did the install. This one works great. Its 16v-30a. If you have a Ring Pro, you need this. Don’t get a 16v-10a or anything less than 16v-30a. If you have a long run to the doorbell (more than 60 feet from the transformer) use a 24v-40a with a Ring. I tried to get away with my old transformer for my Ring Pro and I did for a while then it died. Even before it died sometimes it would not fully ring my mechanical chime or drop WiFi connection with a low voltage message.
Review: Fixed my Ring Pro doorbell issue! - I was skeptical about buying a new Transformerfor my Ring Pro door bell when the one I had worked just fine for my mechanical doorbell before putting my Ring doorbell. My issue was the Ring door bell would only ring about half way or would not ring at on on our chimes but would make a sound in the app. I switched from a mechanical chime to a digital chime figuring that would take less power to make a full chime. But still had the same issue (half or no chime at all). Customer service told me the voltage was a bit low on my transformer and at night when I wanted my video doorbell to work most it would lose power and stay offline all night. So, the first thing I did was buy this transformer and install it. The amperage was showing higher in the app (not much but some) and it stopped dropping off line at time. It also started to work better but still sometimes only part of a chime and not the full thing. Another call to customer support and they adjusted the duration of how long the voltage is sent to the chime in our hallway. Well, that finally fixed it. So my fix was two part. I needed this new transformer to keep my Ring from dropping off line at night and Ring Customer service to adjust the duration of how long the power signal is sent to our chime. There is still about a two or three second lag from the time I push the Ring Door bell until the chime in the hallway starts to chime. That bugs me so I got a "Ring Doorbell Chime" and pluged it into the spar bedroom outlet. Now when you push the front doorbell the Ring Chime makes its tones and just as it is ending the hard wired chime in our hallway starts to chime. Still kind of bugs me but at least i hear something right away and the door bell is staying online 24 hours. Easy to replace and worked great!

### ⭐⭐⭐⭐⭐ Excellent Quality
*by A***. on June 30, 2023*

TLDR; Good quality transformer for wired doorbell camera and address light. Slightly larger Much better heat management. Barely warm compared to the too hot to touch cheaper one I got prior to this upgrade. Has a safety feature that shuts off if there is a fire hazard. Spend the money on this for peace of mind. Details: Unit itself is quality. It is made in china to Broan Nutone specs which is a US company. You would be hard pressed to find anything made in the US now This works with blink doorbell camera and to power my address light. Has sufficient juice and does not overheat. My old one which came with a house built in 2000 was a 16v 10va. It could not provide sufficient power to support a ring, blink, nest, arlo, eufy, Wyze doorbell camera. Bought a cheap unknown brand replacement with 16v 30va specifications but it got too hot to the touch. Normal to be hot. Some say 100 degrees is normal. Some say up to 120 degrees is normal operating temp. I can tell you it got way too hot and I was not comfortable sticking with it. Winded up paying double the price for this Broan Nutone unit and it is a significant improvement. No longer hot. Barely even warm. Size is bigger and I imagine it’s a better heat sink. So I guess size does matter. Minor notes Box came damaged and fins bent. Didn’t have to use them but bent them back using pliers for aesthetics.
