Great design, sturdy build
Appears to be well made, and well-designed. Front cover is easily removable, and adjustment instructions are good, even has a locking plate to hold the pressure screws in place. Electrical contacts easy-to-access. Removed one star because there's no description when you buy it off of what the connection is. It appears to be a 3/8 flare connection. Haven't used it yet, if it does not function as it should I will update this review.

The range is what shows in the photo. The comments of a lower range are wrong
