Having worked in the controls industry for over 20 years and having been a fan of Belimo D/C actuators for almost as long I was very please when Kele started offering these actuators through their website. It makes ordering them as easy as point and click along with the tracking and shipping emails you get makes my job very easy. Belimo is a standard with A LOT of customers and in the event of a failure they stand behind the product as well as they stand next to it. It's as easy as eating cotton candy.
Pros: Good value
Yes, I recommend this product.
