I have used a number of shaving oils inmy time and this is one of the better ones. It's easy to apply and generally gives fair protection with multi-blade razors.
The downs sides are
Cost - it's quite expensive
Fragrance - it's distinctive (though it doesn't linger so only really an issues whist actually shaving)
Pump - the product is dispensed via a pump which is difficult to start and difficult to control the amount dispensed.

However, even withthe downside, the key purpose works well, and it's what I use day to day.
