The packaging for this was quite good. It came folded up, bubble wrapped, braced with plastic styrofoam on the sides, and secured in abwell fitting cardboard box. This box is then secured in a second double-thickness cardboard box. Just a bit more evidence that the company really does care about the products they make.The fold-out portable solar panel is very well designed. It folds up well, and the velcro is good quality so no need to worry about it falling open unexpectedly. It has a nice pocket on the outside (which house the panel's MC4 connectors) in which to stow cables and adapters.The cable is a bit short, but has multiple adapters built in so you can output from the panel's MC4 to Anderson, XT60, or DC5521.The panels seem sturdy and rigid, so it should be very durable. They are also textured on the top, which can help capture more light at slightly off angles, but will also reduce the amount of power generated under more optimal conditions.While the quality appears to be great, it appears to be built using older technology. The panels are inflexible, and it is a bit heavy for the 100W of power generation.One issue to note - the product is listed as IP67 on Amazon and my invoice, but the box lists IP65 and the instructions say not to use it in high humidity. Due to a combination of uncertainty of moisture and dust resistance, mixed with the weight to wattage, I did not bother to test the output, as it will not be able to serve my needs.If you are looking for a way to recharge your storage battery for phones, cameras, overnight LED string lights, etc. this should work quite well. If you are looking to run equipment or trickle charge an EV in the field, the generation from this panel set alone may fall a bit short.

This was about $100 cheaper than any other 400w folding panel so it seemed too good to be true. I took a chance on it. I was able to get about 240 watts. This was at 3:00pm in early April in Ohio with some thin cirrus clouds. That's 1.66 $/watt and I'm sure I could get more out of it in optimal conditions. I haven't tested anything besides that but so far it's great for the money. It's too big to fit in any standard trash can faraday cage though

Hooks up to my ecoflow, works great so far!

Used this to charge 100W my giant backup battery. Got it fully charged in about 2 hours of full midday sun. Couldn't be happier!

Easy to maneuver, I have to say it's a little flimsy though, I guess that's why it's lightweight
