1. The hand wands point of contact to the pump is a plastic nipple that the wands hose slips over and clamps to. The first time you create any kind of stress to this connection it snaps clean off.
2. The battery when fully charged will not last long enough to empty the 12 gallons. In fact I'n able to spray about 9 gallons before having to recharge.
Correct these 2 items and you have 5 star review and not the 2 I gave it.
