Review on SadoTech'S Wireless Doorbell Kit: 1000-Ft Range, Waterproof And Loaded With 52 Chimes And LED Lights by Jason Ingram

Works great and easy to set up for about 1.5 months now. There 3-4 volume setting and a bunch of ringtone. You can listen to them on their website, but for me, I just use the standard doorchime.I set up each door presser to have a different tone. One is for the front door and the other one is for and elderly usage during emergency.As to how to sync and set the tone, check out that one video on YouTube. It is pretty straight forward.I wish there is an even louder volume. Not saying that volume 4 is not loud already since it still does give me the jump at times when the door bell is pressed. But for my own practical usage, it would be nicer.Also, another reason for purchasing this system is that it look nice and can always buy replaceable/additional chimer or door presser if it malfunction. After prolong research, a lot of the system is a one time usage where if one die, there no replaceable part to buy and you have to purchase the whole system again.Pricewise, it not that cheap, but if I consider it in long term, then it would be well worth it.
