I like this panel, but I liked it even more before the latest ten dollar price hike. I bought this panel for $82.99 and now after just a week it is $94.99. Personally, I think I got a good deal for a very good panel (I actually bought two of them) and I am pleased with my purchase. Now there's only a five dollar difference between these and the branded Renogy panels.
I based my purchase on reviews done by Will Prowse on youtube and I liked the performance given by this panel at the price point at which I paid. There are other panels out there that will perform similarly for less (and since the price hike, about 20 dollars less) but my experience is only with this panel.
Now, about how it performs: I am finding that the power output is adequate and expected. Remember, no 100W panel actually puts out 100W of actual power. In DIRECT sunlight, and I do mean actual direct sunlight with 100% of the panel illuminated, I am getting steady 17v at roughly 120 to 130 watts (Please note, I have TWO of these panels, in parallel, so my wattage is doubled here, so each panel is putting out about 60 to 65 watts into my MPPT (EPEVER Tracer 30A) charge controller. If any of the panel is shaded, the wattage drops considerably, but this is common. I was hoping for a 30% loss instead of 40%, but hey, I'll take it. Compared to the Harbor Freight 100w setup that is directly beside these panels, it is exactly doubled, which would also be expected. I have two watt meters connected post-panel, pre-charge controller to measure these values in real time. Does it outperform the HF setup? at 84 dollars per panel it does, versus the 150 you're going to have to buy the full setup for at HF.
This is an actual mono-crystalline panel, it has the dark black look to it and is aesthetically pleasing. I found the quality of the framework to be good, and the connectors on the back were were marked with a label to eliminate any confusion as to polarity. It is a panel on an aluminum frame, so any mounting you will have to do yourself, so your mounting options are up to you. There are poly-crystalline panels that will perform as well as these, at the cost of being slightly larger. I highly recommend the reviews by Will Prowse as I mentioned before, as I am new to this (I consider myself a hobbyist, now) and found them very informative and could watch this very panel be tested against other panels in its class.
Packaging was adequate. It was in a box with some foam around it, but the tape had been torn in a few spots and the box was beginning to open, but I found no damage to the units whatsoever and they operated right out of the box.
So, do I have any complaints? No. I got exactly what I expected.
Did they make false claims? Absolutely NOT! Well, the whole industry does with the advertised wattage of panels, but I got the product I bought.
Would I buy it again? Definitely not at $94. I think for 40% loss I would spend an extra hundred bucks and buy four poly-crystalline panels and quadruple my power output. However, I am not disappointed in my purchase and have no regrets over buying them.

Excellent panel that will no doubt last for decades with proper care and storage!
Reviewed in the United States on March 23, 2020
I gave this product 2 stars for presentation because it arrived with the box half open and all of the included hardware was missing. A slightly less conservative approach towards packing tape may have easily avoided this (there were only 4 strips of tape, one near each corner).The panel itself arrived in immaculate condition!It appears to be very well built. I went over it thoroughly and I can't find any detail that was overlooked through manufacturing. Even the caulking has 100% coverage! I typically expect to "reinforce" the waterproofing on most products like this. I am looking forward to installing it on my camper, but it appears I'll need to order more hardware before I can install it.
