Outstanding service. Bought one of their controllers, 11months later 2 of the relays broke. Contacted them, no fuss, honoured their warranty, sent a new set. Great product, great service.

In 08/25 I bought a new product a Dewenwils Smart Timer for pool pump (120volts). I used it less than 2 months on my pool last year. The timer was put in the garage until June 2026 when I openned the pool. However the device did not work , the device is not working. and DEAD. Guess what there is no US NUMBER TO CALL only an email. The support response : yes there is a warranty if 365 days but only if you buy from this website that is representing the company ( Dewenwils.com)!!! This was not indicated on the box!!! This is garbage company selling garbage for good money and they know it is garbage!!!! Absolutely no support while claiming 1 year warranty on their products . Would nor recommend this unit or anything else this company makes and sells!!! A "Heavy Duty unit" used properly that did not survive 2 months. 0 Stars would be more appropriate.

I bought 4 Dewenwils Pool Pump Timers for two 240v pool pumps, one for 110v pool lights, and one for 110v water features. They’ve been running flawlessly for 3 years on different daily routines, integrated with Amazon Alexa for additional flexibility. I had to replace one of them after two years. Expired warranty. Saved thousands vs an integrated system like I had at our previous home. It was a pain running all the connected wires through conduit and it doesn’t look pretty. The WiFi Blackhawk router is about 50 feet from the outside boxes attached to brick. No issues. Recommended for DIYers. All weekend project for those comfortable with wiring.

During a time when so many products are either garbage or force you to accept tracking along with full functionality, it’s wonderful to find such a useful, affordable, and well-made product.

Great product (remote dimmer control)

This is the second DEWENWILS 200W Low Voltage Transformer I've purchased, and it’s been excellent. The voice and app controls are very easy to use, and the zone settings allow me to manage different outdoor devices separately. Plus, their website offers fantastic Black Friday discounts, making it a great deal for high-quality outdoor lighting control.

Their customer service is by email. The google contact phone number is not a USA number. Overall customer support is inadequate. I'm having problems with my transformer and can't get help to fix or replace. Time is ticking on the manufacturer's warranty deadline. No personal contact. You should have a human that speaks your language help.
