The product arrived on time and does exactly what they say it does it is a good quality unit and at a very affordable price and value for money very efficient and save a lot of messing about should have bought it sooner

been using this for 6 months and it has just failed, dont know what to do now as this was installed in the walls

I am happy with this purchase. I bought one for my doorbell and one for my brother’s doorbell, and it works great. No issue for installing. There is enough cable. Easy to have a constant power supply to the doorbell. Recommend buying!

Easy to install and works perfectly well. Would have been nice to have the option of a longer power lead.

This power adapter keeps RING DOOR BELL 2 charged but the outer casing of this transformer gets very hot. I am anxious it may over heat. Now disconnected. Ring have advised me VIIVRIA Is NOT compatible with Ring doorbell 2. Ring don’t advise purchase because a transformer is unnecessary. The Ring doorbell 2 can be powered by battery or hardwired to existing doorbell. If a transformer used than you must purchase a resistor to work with the transformer (25 Ohm / 50 Watt wirewound). This electronic resistor is essential. It replaces any mechanical or electronic doorbell and makes this (alternate) configuration work successfully. Ring also advise that wires should be soldered onto the resistor and a wire clip can be used on the other end. This unit is a waste of money and is potentially dangerous -- especially as the resister isn't installed. That's not acceptable. The seller's description of functionality purpose and suitability is inaccurate if not potentially dangerous. This transformer should not be marketed as appropriate for Ring doorbell. I requet refund of my money and Boost Deal -- please re-write your product display on Amazon.

Ding dong!Easy set up and no concerns over battery life!

Works perfectly, no problems. Far cheaper that buying unusual size batteries for my camera doorbell.Easy to extend if required a little soldering and some heat shrink would do the trick.

Doesn't really work. My doorbell battery was slowly dropping by about 1 pc per day so not doing the job so sent it back.

Mi è durato 3 giorni, dopodiché ha smesso di funzionare, ha anche la presa americana, quindi ho dovuto acquistare un adattatore a parte, sconsigliato.
