I've seen the ugotadeal seller quite a bit on
eBay. Never did business with them but they seem legit for the most part. I mean if you have problems you're probably screwed. You're taking a
little bit of a gamble but not much more.
The P880PRS is a competent and very decent HU. If it does fail it's not likely to happen within a year or two anyway. You get no warranty as others have mentioned but for the price savings it's worth it IMO.
I mean anything can fail, anything can arrive DOA, but it's not all that likely. If it's DOA, usually (even with
eBay sellers) you'll get an exchange at the very least. If not it's probably going to last longer than the warranty before it does fail (if it ever does).
Buying quality products like the P880PRS has it's benefits in that you're
usually getting a quality, reliable product.
Personally I would take the gamble of no warranty (and I have on many occasions without problems) just because of the $$$ savings.
It used to be that big companies like Pio would honour the warranty regardless (as long as you have a receipt) but it seems they've all gotten wiser to the grey-market internet sales of stuff and therefore try to screw you //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif
I find it a little ridiculous that manufacturers force the stupid "authorised dealer" BS on you. I mean they made the product, it's brand new, sold by someone that provides you with a dated receipt--they should honour the warranty. It's unfortunate manufacturers have chosen this route just to make money. I guess this is another topic though.
As for it being a refurb I completely disagree with "only buying new". I've explained this before... Refurbs can actually be better than new gear, it all depends. If the item was refurbed by the manufacturer or the manufacturer's authorised party then a refurb should be good; if it's refurbed by a 3rd party I'd question it though. There are cases where refurbs tend to present problems but to know that you have to get replies from owners of refurb P880PRS units. Again you're taking a gamble but if feedback is good and their policies are good, and the savings are good, you might be making a very good purchase.
