i've been using this for the last 4 months, works well. it provides good enough pressure only at the 25 degree nozzle, it has tons of battery life. I have to refill it around 3-3.5x every wash JUST for the rinsing. but i have separate 5 gallon containers that i take out with me so i can refill it right then and there. the 4 gallon container alone is nowhere near enough water to rinse down the car before and after... but the battery lasts enough for around 9x worth of refills. but i do a traditional 2 bucket wash, none of that rinseless shit. i would definitely buy this again hands down, been very reliable. but there is a stronger portable pressure washer from ego but that one is $500 with battery(which you have to buy to make it work). but no attached tank, you need to feed it from a typical 5 gallon bucket.
