    Shipping fast.Product quality excellent.Price fantastic.Review by catman3377
    I was having issues with dry eyes and wanted to know what the humidity in my house was so I knew what to set my whole house humidifier to. I bought two of these, one for each level. After about ten minutes I had unwavering humidity levels. I was able to set my whole house humidifier accurately to provide just enough humidity to get my house to an appropriate level - and had the ability to monitor the changes easily.

    I've been using these monitors for four months and they have continued to be perfectly accurate and I'm even buying several for my family members and one for my workplace. (Posted on 10/25/11)
    Fast shipping, thanks for the great productReview by zero87inc
    Arrived in good shape, well packed. Others have questioned the accuracy, I'll try to address that. First, this is not a scientific instrument. If you need high accuracy, you have to pay a lot more. It seems to work well, takes up little space, and is inexpensive. (Posted on 10/25/11)
    Good transaction, fast deliveryReview by ibeie
    I'm using this to keep track of the temperature and humidity in a chinchilla enclosure. Chinchillas (the Andes rodents) are extremely sensitive to heat and humidity, so it's important to keep their temperature correct. I've tested this unit against a hygrometer we use in my lab (calibrated, regularly tested) and it compares perfectly well with that one. (Posted on 10/25/11)
    good product,good sellerReview by sophiek5
    I purchased 4 of these units to track the efficiency of a new mini split system we had installed in our home.
    They work as advertised and by moving the units around I found them to be very consistant in the readings we obtained in the various rooms. For the money they are a great value and I would recommend them to a friend. (Posted on 10/25/11)
