when it got here it didn't have any wires attached to to and I wasn't sure on what end to solder whe wires. to make it worst the side that did need the wires soldered was cut by them so bad there was only a millimeter of the metal left where to solder the wires and these strips go a long way before another cut off point where you can also solder. It ended up coating me a lot of the strip I don't know how well it works because I 2dodnt turn I turn in last night because I was too mad. In the first photo that little little brown spot at the begging is how much room they left me to solder the strips.also don't rush when you buy and read the description these are 24v but 12. I have 24 but you might not.
Good product. The SP105E Controller comes assembled at Led strip. It's good. Avoids mistakes. The only problem is that the SP105E Controller needs a 24V driver, so I should purchase it locally. (and a good one is not cheap). the APP is good and conect easealy tho the SP105E Controller. The only thing, the app is designed for many kind of GRB strips, so in the APP setup, you must chose WS2811 to create effects. You must choose one of the hundred effects (the are very good and pretty enough for many proposals), but You can't create a new one. You can control the speed and the brightness. After you unplug from electricity, and turn on again, it keeps the last color pattern chosen. But in general, I recommend the product. I'm satisfied.
