Customer service is extremely slow.  My product started failing to take a charge, we contacted the company in june - it took them 6 days to get back to me - plus i had to chase them down by voice after emailing their cs dept failed to get any response (per the website).  Then they promised to email the rma instructions -- which took several days -- but they sent the wrong ones (sent retailer instructions).... when i responded that the instructions made no sense - they finally sent the correct instructions.  while waiting for their emails my husband tested the adaptor w/ a multi meter to find out it was just the adaptor that was failed (and since they expected us to pay to ship the whole unit back we didn't want to pay to send back the whole thing) -- i requested if i could just send the adaptor -- (btw - their emails are also full of spelling errors and they could not get my name right),  it took THREE emails to explain to CS what an adaptor was... ! ... then 7 more for them to promise to send one...  that was july 7.  2 days ago i still had not received the adaptor - so emailed once again asking where it was... was told 'sorry it's being mailed today' .... this product is used the most during the summer for us - we use it camping and at the drive-in, picnics etc etc  -- and we have had no ability to use it (cause we cant charge it) for all summer... then after they promised to ship the part a month ago i find out today not only was it not shipped at all - it was sent snail mail today from California (across country to VA) after i asked them and 'reminded' them -- so the likelihood of us getting this time for our next use requirement (this weekend) is highly unlikely.finally - its sold as having a compressor capable of inflating truck tires -- it does not. it does not create enough pressure to inflate our 17" truck or rv tires..  (we had to buy another dedicated compressor for them)A company is only as good as its customer service - and they have failed at every point for theirs.  not to mention a simple power adaptor should last more than 6 months.  the item is useless if you can't charge it.  I cannot recommend this product.
