TFA Bel-Air Funk Thermo Hygrometer weiss

So far this has performed well. Temperatures and humidity readings seem accurate enough. The ventillation tip is an icon that tells you to open or close your window depending on the internal humidity levels. Bit of a gimmick and no real value. Mine's in the kitchen so it bounces about all over the place!I am not sure about the longevity of the external sensor as it has dropped the signal once I have noticed in a week. Could be the batteries going (I used rechargeable batteries so that could be the issue)but they are only about 4-5 feet apart (window separating them). I am also not convinced the exterior sensor is all that weather proof but in my experience none of these sensors are. I'll update if things get worse!

Very professional looking and well made.Since I installed both base unit & outdoor sensor it has come alive and working doing its job.I decided not to put the outside sensor outdoors because I don't think it's 100% weather proof so instead I've got it in another room.I'm very happy with my purchase the LCD screen on the main unit is very clear as is on the remote sensor.I highly recommend this and the accuracy is amazing as it constantly updates every 16 seconds (base) 4 seconds (remote)Professionally made & accurate.

Very handy. It shows both temperature and humidity indoors and outdoors, exactly as it says on the tin.Had to come back and amend as I had to return it as it has now lost the signal twice and I've had to remove all batteries to make it work again, such a shame! Just hoping it's this one unit though, I'm ordering it again. At this time I had to drop from 5 stars to 3.

This has continued to work really well from the outset and gives an accurate measurement of in and out temperatures when measured against more traditional methods. The screen is very easy to read, if perhaps a bit garish, but for anyone interested in gadgets, this one is good fun and effective. Do heed the warning to keep the outside transmitter free from moisture, ours got drenched in a cloudburst and stopped working for a while. The display has not worked since but accurate data continued to be transmitted once the unit had dried out.

This is the second one I have purchased as they work exactly as they should and are accurate enough for my needs. The remote sensors have a good range and work very well.
