Mistake #1 I ignored bad reviews of the clips that you can attach to turn corners & ordered them.

The seller reached out to me because i gave them a bad review, and sent me two replacement strips that work well

Wrote a poor review yesterday because adhesive failed to hold on ALL strips installed.

I was supplied a sample of the product for test and review and I promised to provide a fair and honest review.

Re polarity: There are lots of negative reviews for LED strip connectors (again, these don't work on this product as discussed above,) complaining about the fact that sometimes the positive/negative polarity is "wrong".

FORMER REVIEW- Super for under cabinet.
