So far no problems except it tends to overheat when in a bag. I also broke the hook on the strap so can't wear it over shoulder

Pretty good service. Shipping was on time.

The problem is the batteries do not last as long as advertised. Tested on a setting of one is not what I would expect. At lest a setting of 2 would be more realistic. Plus the hose crimps at the Spicket or nozzle. Have tried using straws and tape to hold upright so it doesn’t collapse.

3 weeks into use of the G5 I am very happy with the design and performance. Send me a survey in 6 months and I will give you a more thoughtful answer.

There should be a less expensive way to charge the extra battery.
