Does absolutely reliable with me

I made the switch for 5 LED lamps in use, since about 1.5 years. I can understand the assessments concerning the lack of reliability not confirm. I turn on the light on the one hand on the AB440M and additionally over the AB440R (keyfob). Both works absolutely reliable. The batteries I've never changed, the distance between wall switch and built-in switch is approximately 5m. The switch is operated several times daily.

The only downside is that when you stand in front of the switch, the range drops significantly. That is, if I between radio (wall) switch and receiver stand, the reception is usually interrupted. If you know it, no problem - with a switch but certainly unusual ..

In my view, still a good product.
