Quote from caotico :
I'm curious what the argument for getting 100w vs higher wattage is. Obviously the price is cheap, but are you just having to have significantly more surface area for the same wattage? I guess I'm wondering if there are any pluses to lower wattage panels.
What are you talking about? This is actually smaller than most 100w panels which are 41x23. If you go for bigger wattage the panels get huge

Quote from PurpleScent2237 :
more and more AliExpress ads
I'd usually take it over Amazon. AliExpress Choice/US-warehouse is Aliexpress-fulfillment just like Amazon fulfillment. People buying from shady sellers directly on Aliexpress isn't much different than buying from shady sellers on Amazon - both are simple marketplaces with a lot of counterfeit goods, and few reputable name brands (same with Walmart, Newegg, eBay, whatever other marketplaces). The main difference is that someone else typically buys the things from China, puts them in Amazon warehouses, and sells the same generically-branded thing for a markup. Sometimes that markup is 2-3x.

Aliexpress using Choice shipping also provides return labels for goods, and something like 5 items per month. If it's more than that, Amazon or elsewhere, that's likely return abuse by the end user.

I can't even take Amazon returns to a Locker+ anymore for things that are fine, but like a general store return. Amazon shut this down about a year ago. Amazon offers nothing to me now days other than higher prices, and similar return policies.

It's just the way things are now days - the niceties of Amazon from 15-20 years ago don't exist today. May as well cut out the overpriced middleman, or otherwise shop local B&M.

I used to feel this way, but I gave them a shot the last few months and have gotten some incredible deals on LEDs, connectors, wiring and other things that would have cost me 4-10x as much anywhere else. Fast shipping, too.
