  1. Still happy after one week! 5 Star Review

    Posted by on 14th Jun 2020

    Easy to set up. The instructions are very comprehensive. Easy to get online as well, sending data to the Weather Underground. Not sure if it's possible to send to an alternative website. I haven't figured that out yet. The console seems to work well, providing a good range of different data, although feels a bit 'plasticky'. I would like the option to be able to customise it a bit more. The main interest in my location is the wind, so I would like to have that centre stage on the console with a graph, showing windspeed trend over the past 24 hours. Talking of wind, the anemometer again feels quite 'plasticky' and lightweight. We'll see how that lasts when the winter comes. A lot of anemometers get destroyed by the wind here. The anemometer on my David Vantage Pro got blown apart after about 8 years. I notice that Aercus has spare available at a reasonable price. The whole communication and upload side of things seems a lot more 21st century than Davis - which is why I went for Aercus

  2. Comprehensive weather data, easy to set up 5 Star Review

    Posted by on 10th Jun 2020

    Greenfrog Scientific very responsive, with quick delivery. The comprehensive online guide gave lots of helpful background info about how best to locate and set up the weather station. Once we'd chosen the best site for it, everything worked 'out of the box' - just needed batteries and the pressure calibrating for our location (clear explanation how to do this). The online wunderground data link is clear and works well.
    A high quality weather station at a very good price. Recommended.

  3. So Far So Good 4 Star Review

    Posted by on 10th Sep 2019

    Excellent Service. All worked first time I Bought this as a replacement for a Maplin unit which failed twice following Power Cuts. Lets wait and see If this has the same problem, at least Greenfrog Scientific allow you to buy a replacement display unit (By the way their display unit does work with the Maplin sensors)

    Over all very pleased with Greenfrog Scientific and the product.

  4. Great service 4 Star Review

    Posted by on 10th Apr 2018

    Purchased this product about 14 months ago. Worked really well and then the sensor unit stopped transmitting. Contacted greenfrog and they replaced it without any quibble. You couldn't ask for better service

  5. bon produit 4 Star Review

    Posted by on 19th Dec 2017

    Livraison rapide, emballage soigné, installation et paramétrage faciles, pour l'instant pratiquement que du bon sauf l'appli qui n'existe pas sous android, pourtant il était notifié que oui.
    C'est ma sixème station météo et la première de cette marque, pour l'instant la meilleure.
    A voir dans le futur la précision et durabilité des capteurs

  6. Easy to link to Wi-Fi and internet 5 Star Review

    Posted by on 10th Nov 2017

    Before ordering this product I had taken delivery of a rival product but could not link it to my home Wi-Fi. It could only be set up using a smartphone (in my case Android). After returning it the retailer said that the problem must be with my WiFi as it was fully functional. I actually wonder if the product was designed for iPhone and not well tested on Android.

    Before ordering the Weather Ranger I looked at the extensive documentation online and liked the fact that Wi-Fi set up was by entering values on the base station - much lower risk than via a smartphone app. I also liked the extensive range of settings available.

    The Weather Ranger worked out of the box and there were no issues setting up Wi-Fi and getting readings to Wunderground. It has been running reliably for 10 days and so far I think it is a great product.

  7. Quality weather station at a sensible price 5 Star Review

    Posted by on 5th Mar 2017

    I had been looking for a weather station with solar for a while and all were very expensive but this one isn't. Love the Wunderground display of my weather info I can access online or in app from anywhere. Data download needs a memory card but with all the data stored on console I haven't used it yet. Set up relatively easy once you get used to the console arrow buttons used to navigate the menus. Nevertheless a great bit of kit.

  8. Easy to set up, works well 5 Star Review

    Posted by on 2nd Dec 2015

    Only had it a week, but it was easy to set up - the wireless is good enough to reach from the barns at the back of the farm through thick walls of an old farmhouse. Setting up the Wunderground was straightforward, so was getting it on wifi, so it's all up and running quite easily. Time will tell if the sensors last and the device stays connected, but so far so good.
