Familiarity: I've used it several times
Worked great the first time, albeit, the reservoir cover is unnecessarily hard to open. After the second use it started leaking. At first I thought maybe it was operator error, but after several more attempts--I realized it's just a design flaw. Too bad, they usually make pretty decent products.
