The power is good, and the unit is comfortable to wear. My qualms are that: tube is a bit short for a tall person and the handle is too high which leads to fatigue.

The vent in the gas cap was constantly falling out when refilling. I finally lost it. The cost of a new one was quite expensive for what it was (a thin cone of soft pvc). Without it, the gas leaks out on you. I fashioned one out of a square of shower curtain (also pvc).
Also, the gas can could be larger, and the on/off switch easier to read (i.e. a label rather than raised black plastic letters).
Customer service is "forum" based (where you summit and then go back when your question has been addressed), which I'm not a fan of.
