This is not a water heater. The water pump functions excellently. Packaging was very good.

The service and delivery speed were excellent in central Mexico, and the tracking status updated accurately. The product works perfectly; I tested it immediately. The water pressure is great, like a regular shower. Keep in mind it's not cordless or rechargeable; it needs to be plugged in, but the cable is long enough and has a switch. The pump feels heavy and well-made, but the hose and head feel light, though well-crafted, and potentially fragile. I loved it and am satisfied with this purchase; I hope it lasts a long time.

So far, excellent performance, I hope it lasts without breaking down. The shower works very well.

Simply very good.
