I have used the V3 and V4 lightstrip. Both work identically within the hue ecosystem but all the connections are different between the 2 versions. Currently there are no V4 connectors on the market which makes it extremely difficult to complete custom installations. The worst part is that the box contains a single cut end to cut end connector but there are no other similar connectors on the market that i can find.
That said, the lightstrip themselves are great. I'm about 20 devices deep into the hue ecosystem. Some time to configure the device is required and the app is fairly intuitive but once you get started there's a lot you can do.
Side note: not sure why this review is asking my rating of motion detection. The lightstrip does not have motion detection integrated. You need to purchase a motion detection sensor separately and configure it, if that feature is required.
