I'm not a big fan of Plot Saver. I know it can work though. You know the picture they show of the plot split in two - 1/2 protected - the other half open for grazing:



I tend to think that the very fact that the deer have an area to browse - other than the protected area - gives the illusion that it works better than it probably really does. (maybe if the whole plot was unprotected - the deer would only graze it 1/2 as much as the FULLY grazed section pictured?)

For me - What it really comes down to is that if the deer population is so high that I cannot grow a plot - then I need to reduce the poulation - OR increase the plot size. I know not everyone has this option - but I only see products like Plot Saver as a temporary fix to a real life problem - that can be solved with other management systems.
