Previous bell worked for years in same location but as the years went on was having to replace the batteries more regularly. So did a search for a replacement bell and on finding the Tecknets which required no batteries I thought, Brilliant.
I have now purchased two Tecknets doorbells, first on Amazon and second directly from Tecknet.
Second was purchased as first didn't work in location the old original bell had worked in fine for years.
I liked the bell and the concept of no batteries so thought I'd buy a more up to-date model (longer range) but unfortunately same problem.
Between bell and receiver less than 10 metres distance and a plastic door.
I could blame the door or whatever else, but previous bell worked fine for about eight years! Tecknets bells look the part and good quality, but I've had no luck x 2.

Very good product works well

Door bell fine, tunes, not so sure,used the double sided fixing, found the bell had dropped off after a few days, used the correct method,plugs and screws

Delighted. Easy fix; works wll.

Lots of tunes to choose from, bell (sounder) plugs into internal socket. The range isn't as far as advertised. With sounder in living room it doesn't always work. Moved bell to hallway & it works better.
