Just wanna say thank you to Kohl’s for the fast replacement pan shipment of new device excellent customer service

Faulty / Broken upon arrival

I hung the meter from my tent and right off the bat was getting inconstant readings. I tried to level it out over a weeks period to no avail. I returned the meter for a refund and went with with another brand of meters. John was very helpful and easy with the return transaction-


Its just ok a little expensive for its worth.

No stress, just fun!

Honestly it’s rare for me to rate 5stars on products and services, being picky as I am. But Pulse deserves a 5+! This product literally made me fall in love with growing again. I was used to grow outdoors but due to personal life changes I was “forced” to move to an indoor system and even knowing the basics I battled for over 3 months getting nothing but killing plants. I wasn’t able to get things right, my setup was good, I knew what I was doing but I was missing something, my plants weren't developing and I was puzzled and frustrated. Little did I knew that my old meter (Temp/RH reading only) was way off calibration causing all my problems. Pulse arrived and in a very short period of time I was able not only to literally save the plants I had but also to watch their exponential growth. I couldn’t believe my eyes! After all the stress and time wasting I was finally enjoying all that again and having fun while growing. The product is beautifully made, sleek on appearance, has the right size and shape, very easy to setup, literally plug&play! The app is wonderful as well and it did not slowdown my phone. I still need to figure out one little thing on the app (time/clock) but it doesn’t change my overall impression at all! I cannot overemphasise enough how much I love it and recommend to others.
