GadgetsGo sells great products. However, most importantly to me, is their excellent customer service. I had a question and it was answered with a personal phone call within hours. Then they followed up with an email.
Advantages: The tankless water heater that I purchased performed better than I expected and better than it was rated on the box. I bought one that was rated for 1 shower and 2 faucets at a time. However, I had the dishwasher running and my grandson didn't know it was on and he took a shower at the same time. It performed like a champ. This was my first one and did not know for sure what to expect. It had a problem and still performed beyond its stated capacity. This part was shipped immediately to me without question. This water heater is simple to set and to change the temperature as needed. Just a turn of the dial and it is an immediate change. I have no problem recommending this brand to anyone who would ask me.
Disadvantages: So far I have had no disadvantages to this purchase. This was an excellent purchase for me and I am so impressed with this company.
