China made LED light Strip problems.

I've installed a couple of LED light strips, one down each bottom side of my motor home. I purchased them online for around $25, they flash, change colors, dim etc etc. I've had nothing but problems, that I've narrowed down to a view things. one being voltage drop, which makes the lights act erratic, ie, different color then selected, only 1/2 the lights come on, etc etc. I've increased the wire gauge size, soldiered all connections, and it works about 95% correctly. I've researched online, and it appears there's lots of problems with these so called cheap China made LED light strips. The light strips themselves are thin, cheap components that burn out, voltage drop among other things. I haven't talked to any experts yet, but have read and seen videos that compare the China made ones with domestic strips. The quality of the domestic is superior...........the price also goes up.......but I guess you get what you pay for.
I'm curious, has anyone else run into problems with their mult function, multi colored light strips? Thanks
