I buy this for the spill-proof bit after ruin a few kb . ironically since then - a year - no spill have test it LOL . but for a cheap unit it have a nice approximation of the clicky-ness of a IBM Model 5 -lrb- still the best -rrb- . I have use a lot of cheap unit and the extra metal spine on this give a slightly more solid feel . I do not mind the extra key above Home etc , no prob , but I must admit htign \ \ \ \ itt the backspace key accurately have be a problem . and I be not even a touch typist . other than that , well worth the buck .
