Lower quality window film and usually inexperienced window tinters. The usual pay for tinters there is not that great, so attracts the bottom of the barrel. This is not necessarily true of all locations since they are individually owned/operated, but seems to be true more often than not. Plus they plotter cut their tint and the software they use is not the best. So the patterns that are cut can have gaps. They are usually rated in the low 4's on Google or less... a quick search of South Florida only one had a 4.7.
Doing Pinnacle will probably give you the desired outcome. Our #1 sold film is CTX which is slightly lower performance than Pinnacle and people love it.
