One of the things cruisers often overlook are the requirements for day to day living. Living in remote areas, anchoring where there are small villages or few other people around; the things we need for our own comfort can often be overlooked on a boat. We were lucky, before we left my barberess asked who was going to cut my beard and hair. She knew I never really trimmed my beard because I always visited her looking like a bear.
Upon further thought W/ was elected to be the new barberess. The one I had been going to for years said she would show her a thing or two. She (Lisa) also advised us to purchase a set of Wahl Clippers for my trims. We bought one and it has been one of the best decision made and one that has save the most money.
We picked up a set of clippers for roughly $50 US. We've used it monthly since 2008. Since I have visited a professional barber a handful of times. Assuming a reasonably cheap cut and trim costing 15 bucks we've saved almost $2,000. All with a $50 dollar investment. Not a bad return on your money.
The only complaint I have is that the rubber around the clipper seems to get a little sticky. We don't have AC and the heat from the tropics is not rubber friendly. But for what we have saved, a new one would not be an issue.
I will add that the Wahl from the US only works well on the US power grid. If you try to use it with a step down transformer in one of the 220 V 50 cycle countries you will be deafened by the noise it makes.
It's only for this reason I grade the product with an A-. Would I buy it again. You betcha!
