Sutro gets a bad rap online, but I haven't had any problems with their customer service. Sutro is a must for anyone with a swimming pool. The Sutro Smart Monitor takes the guesswork out of water monitoring and helps you keep your pH, free chlorine, and alkalinity levels in check. The Sutro app also provides real-time alerts, so you can make sure your pool is always ready for a swim.Setting up Sutro is quick and easy, and the customer service team is always available to help if you have any questions. In my experience, Sutro's customer service is top-notch, and I would recommend their products to anyone looking for an easy way to maintain a swimming pool. Thanks, Sutro!
