1. Led strip welded by 0.5m is very normal in an electronic product,not a quality problem.if you mind this, do not place order！

2. IP30: Non- Waterproof

IP65: Waterproof in Silicon Coating

IP67: Waterproof in SiliconTube

3.If the order no more than $5 ,no tracking number !!

this link is not include power supply and led controller,please know it
