Gillette Venus

How many times can a Gillette Venus be used before needing a new one. or similar, do you just use the Gillette Venus forever. Do you need to get a new one each time you use little or something like Gillette Venus regular disposables?

I had the Gillette Venus and this thing has blue tape over the blade and once it disappears or lightens then its time to get a new one. Hope this helps:)

Mine lasts a few weeks many of. there is a blue band on top that disappears when the shaver is not good more

for one month, but I only use it for 4 times
