I've been using this for years, since for me they are best, even better than the ones with 5 blades and has usual this is a great product and original (no chinese imitations here)
They say this pack up to 60 shaves but for each cartridge i was able to use it at least 20 times so by my estimate i would say they last 80 shaves, but it will depend on the type of beard you have.
Definetely a good buy and recommended!
I tried to save money by ordering Mach3 blades instead of the Gillette Fusion range but actually it didn’t work out.
The blades aren’t as good as the Fusion range and feel course so it might have been better to spend a little extra after all.
One benefit is the quantity in the package for the price is reasonable.
