  1. Excellent value 5 Star Review

    Posted by on 14th Dec 2021

    Bought this to replace an existing unit of a different make that after years of good service had started to loose the external signal. This Aerucs item had everything I was looking for at a amazing price compared to other items. I wanted a full day and date display, inside and outside temps and hum. and also barometric pressure. It also needed to be battery operated for where I wanted it to go. It was very easy to set up, however I did find that this also would loose the outside signal depending on where it was placed. It was very easy to experiment with locations for the outside and inside units until eventually finding a good compromise and now it consistently retains signal and works as it should so very happy since my old unit now does not function in any location. The desktop unit is a nice size and details are clearly visible. The readings were also consistent with my central heating thermostat and my original weather station when it was working so it appears to be accurate. The item was received very quickly so all round great service.

  2. Good value 4 Star Review

    Easy set up .I have one of these units in New Zealand . The remote sensor and base station temperatures very close to same reading when in same enviroment . +/- 0.5 degree C . Many do not seem to .
    Otherwise does all I want as a simple desk weather station .
    You get what you pay for , but for £29.95 I think this unit is a quality product for a reasonable price .

  3. Excellent value, does what it is supposed to. 5 Star Review

    I wanted a reliable, reasonably accurate, indoor/outdoor thermometer and barometer and that is exactly what I have. The instructions are a little tricky, but the functions are clear and so far it works well. There are limitations with all these devices - one can never site the outdoor sensor where it will give accurate readings in all weathers. And I have yet to be able to get it to sync with the atomic clock in Germany... but it wasn't bought to do that. Great value and just what I wanted. And it arrived SO quickly. [Greenfrog note: This model does not sync with the atomic clock]. Thank you Greenfrog!
