Byron Sentry BY201F 100m Wireless Portable Door Chime Kit with Flashing Light and 6 Sounds

I have no problem with Byron doorbells generally, but my previous two cheaper models both suffered from interference. They would go off at all times of the day and night (very annoying). (I found some instructions for resetting the thing, but it made no difference. I suspect the chime worked on one frequency and so couldn't be changed.)I've had this door chime for a couple of weeks now, and with no problems at all. No interference :-) I only have a small place, so the chime is loud enough wherever I am. (I have it on the first or second setting.) Yes it is screw fixed to a metal framed uPVC door, but it works fine with the receiver unit in my front room. I don't really need the flashing light (my hearing is generally okay!), but it could be handy should I miss hearing the bell. It flashes with a bright white light about four times after the bell is rung, so you need to put the receiver somewhere where you would notice the light.Overall, I'm very happy with the product. Easy to use and works perfectly.

Byron Sentry BY201F wireless portable door chime kit.I like it very much, in fact several people have seen it and are interested in getting one also.The only fly in the ointment was saying that the bell push could be mounted by using double sided tape on plastic door frames etc, it fell off after about a week, so had to be mounted again by a more traditional method, screws,If it hadn't been for that I would have given this product five stars.

Bought this on 20th Feb, delivered 21st and fitted 22nd. Very easy to fit and set up and great sound from a little unit. Given 5 stars at moment and will see how long it lasts as previous plug in Byron product only lasted 15 months!

Worked straight out of the box with no issues. Have yet to experience any interference from neighbours with similar items. the sound produced is a bit tinny, and I would have welcomed a more normal doorbell chime option but it certainly works and we have no problems hearing it from anywhere in the house

We needed a better door bell system so we decided to change from wired to wireless but we needed more than one chime unit, the choice in local shops was limited so brought these off amazon where we had a great choice of chime units, this one works very good, its small and neat, has a good volume control from quite loud to very quiet, it also has a flashing light that flashes for a short time after the chime has finished, there is a selection of chimes available to programme the bell and the chime, would recommend this product

Very easy to fit doorbell over old position of wired doorbell. Bought for my mother and she can hear the bell easily , and can take it anywhere in the house.

We have been looking for a system to allow our bell ringers to stop ringing when the bride arrives into the Church. Someone suggested this product. We have a wedding on the 21st. September when it will be tested. First trails show that it is what we require

Bought this in June 2019, all good, easy to use. Unfortunately, in September 2020, it has gone quiet and needs replacing. Tried resetting etc, but still not working at the loudest setting. Unable to contact seller through Amazon.
