It's a 30cm wire whisk... but that doesn't tell you enough.
Normally you would look at a whisk reasonably carefully in a cooks' shop or wherever you're buying it. They aren't very expensive, but one which is too light, too short, hard to use or hard to clean is an annoyance that stays in your kitchen drawer for years.
Compared to the cheapest whisks, of the kind you get in Poundland, this one has a decent weight, just right for whisking, is quite long for a domestic whisk, though nowhere near the size of a commercial whisk, and uses the traditional design with a coiled wire handle. It is no more difficult to wash and dry than any other whisk. However, note that it will rust if it goes in the dishwasher! This seems to be mainly around the collar, which is less rust-immune than the whisk bit. Still annoying, though, if you want to do more whisking than washing and drying.
Verdict: as a daily whisk, this is fine. You don't need to purchase a more expensive one if quality is the issue, though some new designs claim to be better for frothing. A true stainless steel whisk would be better, though.
