Ive used Kona Labs LP-2750 for nearly 5 years now without anything negative to say.  Richard is a pleasure to do business with, as he goes the extra mile for his customers. It is a very important tool I use on every pool or spa leak job. I have one in every truck in my business. I recommend this product to anyone in Leak detection industry.

Nothing but a great experience with Kona Labs LevelSmart auto fill. I have used and installed 5 now and has not let me or my customers down.

Easy to install.  Pairing the sensor was a bit tricky (I should have read the instructions more closely).  Distance from the sensor to the antenna is awesome!  Once paired, the unit operated flawlessly.  I replaced the included plastic valve with a brass one so that it would interface properly with my copper piping.  Not a big issue at all.  The water level sensor mounts easily with the included epoxy putty, even underwater.  Water level has been perfect for months now. 

Terrific product.  Highly recommended.

Installed level smart system. Did not have to cut a single pipe. Simply exchanged the manual valve operator with an automatic operator. Works perfectly.
