I was interested in this model a few months ago. Changed my mind when I read the one-star reviews on Amazon.
I never saw your mentioned listing, but I have observed that you really have to look hard at Amazon reviews sometimes. It is very easy to get very skewed reviews if only a few individuals have reviewed a new or barely active listing (and the same product can have multiple listings on Amazon with different vendors). So it often pays to check the number of reviews, then sort on the negative reviews to determine what the supposed fault really is that the parties were complaining about, and all too often it has nothing to do with the product itself but from highly unrealistic expectations or misuse of the product (or just plain not understanding the nature of the product they purchased). It is also not at all uncommon for people to associate negative reviews with a product they never bought or used because for whatever reason they did not realize that the listed air compressor item and that flat can of compressed "air duster" air they bought elsewhere are entirely different products (I see a lot of that in some reviews where it is painfully clear that many reviews have nothing to do with the actual product listed, which really makes one scratch their head sometimes).
In the case of air compressor reviews in general on Amazon, if you actually do a sort on the most negative reviews and then actually begin reading them, one often discovers a number of hints suggesting these compressors have very likely been plugged into undersized extension cords (you really do not want to be using extension cords with air compressors, and if one does it should be well oversized) while others were likely ignoring the maximum rated duty cycle rating of these oilless air compressors (generally rated for no more than 15 min on/off at best). If you see reports of circuit breakers tripping, the compressor stalling before reaching pressure, never reaching cutoff pressure, or the motor burning up, those are almost all the result of misuse (specifically signs of an extension cord being used or use on an otherwise overloaded 120V circuit) by the operator but are frequently reported as defects in the product. Just imagine how many perfectly ordinary weekend DIYers are out there that would happily try to run both a 15A air compressor (which can draw up to 30-40A on startup) and a 13A Shop Vac simultaneously off the same cheap 10ft. #16 gauge extension cord plugged into a single 15A or 20A receptacle circuit and not be aware that they are committing multiple wrongs because they never bothered to read either product's manual (nor the extension cord warning label)!
So it often pays to take a few minutes to dig into the reviews if you are considering a product that should be decent but seems to have unusually bad reviews as I have often gone ahead and ordered items after reading up on the 1 and 2 star reviews and then compared them against some selected 4 and 5 star reviews for some added balance.
That said, I would expect a 1HP air compressor to have a rather low CFM rating versus many of the more common 2+HP (13-15A) oilless pancake/hotdog units on the market, so you may see some negative reviews because it is likely to take much longer to recharge and may not always keep up with some heavier nailing tasks. That could also garner a few negative reviews from those expecting the same level of performance (and not just the added quietness).
