    Item was as-described and shipped fast. Packaging was adequate as it's a pretty sturdy plastic before it spends a couple decades in direct sunlight. Much cheaper to buy this than a whole new filter.

    The relay board was New, as described. It has been installed on the MasterCool and works perfectly. The price was middle of the road from other vendor prices. Shipping was free. It was packed well, even though the outer box sustained some damage, but the product was in perfect condition.

    Had a a bit of a miscommunication over how the listing was represented. Seller went 100% above and beyond what I asked for to resolve the matter. While not everything always goes perfectly - What is most important is the intent and how you stand behind your sales. I cannot say enough good things about this seller. They came through when it counted most.

    Perfect replacement for the humidstat that had failed in my Aprilaire 500M humidifier. 2 screws to attach the control wires, reinstall with 4 sheet metal screws holding it in the cold air return duct, and the house is more comfortable again. Relative humidity is up from 24 to 35% in 2 days.

    Piece of junk

    These things are designed from the factory not to turn on until it reaches 38% humidity which the manufacture says it's reading the humidity in your house. If I had 38% humidity in my house I wouldn't need a dam humidistat would I!!!!

    Nice replacement

    The old one quit working. As I looked for a replacement I wondered if one existed. After a little research this one popped up. The wire connections were the same. A couple of screws and presto. Now the humidifier is working great.

    It was very easy to install and works perfectly. I was replacing the original Aprilaire from 19 years ago.

    Replacement humidstat works perfectly!! Everything was just as promised and delivered on time!

    Absolutely works beautifully!! Went from a humidity level in our home of less than 24 to 31 in a matter of days! It is much more comfortable now in the house!!
