I started to buy SIMARINE products 3 years ago to monitor batteries, tank levels and devices installed in my boat. I sold a boat, bougth a new one and again installed PICO monitor and accessories. The installation and startup is incredibly simple. The instruction manual is so clear. The system is really plug-in and very intuitive to program. And, after 3 years, I can confirm that SIMARINE products are very, very reliable. Never had a problem. About after sales service I have always had an answer, most of the time received within the day. Many compliments and I will surely continue to buy SIMARINE products. Andrea.
