My application is for a EF Delta 2. Box arrived undamaged, easy setup. Providing its real-world wattage with full sun.Location is Indiana at 6PM in July facing east.Pros:Easy setup, plug and play, no gimmicky on board phone charger, just a panel with MC4 leads.Good build quality.Outputs reasonable-accurate real-world power levels.Possible Con(s):-(Long) I feel like I may break it trying to unfold it?. It's a 'rigid' material, which is good, but it does making slight crackling sounds if you put enough pressure when trying to set it up. Like holding it and leaning the panel back to setup legs, I had to press to hold it and with thumbs on front, sort-of like a bending direction to keep it from falling forward. I made sure to hold the very edge, avoiding the actual solar cells. I THINK it's just the material used and it will be okay.- It's heavier than I expected, but if it's durable, that's fine.Conlusion:First day I'm happy with my purchase. It was a little higher on my ideal budget for a portable panel, but better value for 200w vs $450 for ecoflow 160w.
