I have been using gillete guard for more than 7 months and it gives a good shave and saves the shaving time.
The blade is designed in such a way that even if we shave so fast, it doesnt produce any cut on the skin.
The price of this blade is very less as compare to others and also the cost of blades are also very less and for me, one blade lasts for around 5 or 6 times easily.
The only disadvantage is, only one row of blade is there, so need to shave two times back to back to get better shave. Easy to use and perfect for less beards. For more beards, it creates some trouble as one small blade is present. If you want to buy any low budget razer and effective shave, then gillete guard is the best option.
