I had received a defected product, not only did I get a replacement in record time, they also helped me out on the return defected item, when I had a hard time getting to the shipping place to return item. Which took so much off my already busy life!!! They more than made up for the defected item. And "YES" I would definitely buy from them again. ### ⭐ its a pile. *by R***. on April 25, 2025* i ordered the first one,which was pile of crap, I Then ordered a second one thinking that must have been a fluke, nothing can have that ,any leaks faulty circuitry etc, I stand corrected, the second one was worse, like they sday you get what you pay for, and therse dont cost much. find an alternative brand and save yourself! ### ⭐⭐⭐⭐ Check the wattage. *by D***N on September 30, 2023* I cannot use this item for where it was intended as the wattage is too great. We did not know. there was a difference. It looks beautiful and I was so looking forward to using it. Perhaps we can use it elsewhere. I cannot comment on ease of installation or efficiency. ## Frequently Bought Together - Tankless Electric Hot Water Heater Set 4500W 110V Instant Water Heater On Demand Bath Shower with LED Screen Display for Bathroom, Bathtub, RV, Whole House, Shower, Sink Small,w/Overheating Protection - Generic Tankless Water Heater Electric, Instant Hot Water Heater Under Sink, 3000W 110V On Demand Mini Water Heater for RV Kitchen Bathroom, White - KENCIT T33 Automatic On-Demand Diaphragm Pump 115Vac, 4.0GPM, 45PSI, Industrial Water Pressure Pump for Kitchen, Bathroom, RV, Marine Yacht, Caravan, Garden --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/529290284-tankless-electric-hot-water-heater-set-4500w-110v-instant-water](https://www.desertcart.jp/products/529290284-tankless-electric-hot-water-heater-set-4500w-110v-instant-water) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-11-07*
