Extremely Disappointed.  I purchased this premium extensive unit to clean a 20' x 20' concrete patio every year.  I used it to clean the patio right after I purchased it July 2016 - it worked like it was supposed to & took about an hour.  Last August (2017), a month after the warranty ran, about half way through my annual project the wand stopped oscillating, and would only clean a fine pin line at a time (instead of the wide swath that gets cleaned when the wand oscillates like it is supposed to, so my hour long annual project took 2 days to finish. Yes, I tried all the troubleshooting tips to no avail.  This year, I attempted to clean the patio again, but the built-in ground-fault plug keeps popping/tripping every time I plug it in.  It is not wet or damaged in any way, but it won't work.  I tried several other outlets, with the same effect.  I've plugged in other electrical items in the same outlets, including other heavy duty power equipment, and even a different power washer, and everything else works fine.  My old inexpensive Black & Decker unit worked perfectly for over 10 years until the water line started to leak.

Terrible! Awful sound quality, not nearly loud r kin and the microphone did not work! Sent it back immediately! Waste of my time and money (but at least I got that back).

Wore one time - colors faded and stained underwear and other clothes. Very displeased with the colors bleeding onto otherwise clothes. I wore these one time. Do not waste your money. So angry...

This is the worst product ever!  I purchased 2 packs of these (12 total) and only 1 out of the 12 worked. Absolute worst... do not waste your money!

I wish I could give this a "NO STAR" rating - It was a complete waste of hard earned money.  It lasted exactly ONE DAY past the return period before it stopped working!  My recommendation - Find another manufacturer!!!

This is a complete POS.  Used it once, worked great.  Went to use again and it didn't work at all.  Should have heeded the reviews and just made one myself.  It would have been cheaper than this.  You get what you pay for, but not in this case.  Unless you consider 100.00 for garbage good.

Bought this for a specific one time event and it doesn't work.
Apparently not eligible for return and since this is the first time I have tried to return something to Amazon,
I am quite disgruntled!

Stopped working after 1st use - do not buy!  Not worth the hassle of returning.

This thing is a piece of garbage.  It worked exactly one time.  The next time we went to use it it was beeping incessantly and gave us a -99 degree readout.  Don't waste your time or money with this. I gave this to my husband for Fathers Day and now I cannot return it since the window for returns has expired. Very frustrating.

UPDATE - we contacted the seller to alert them of our problems and they are offering to replace parts or possibly even the whole device.  So I am updating this review to reflect the prompt and attentive customer service.  Hopefully they can work out the kinks with future updates because this has the potential to be an awesome product!

Crap. Stopped working after one use. Do not purchase this cable. Connectors are too small as well.
