Comments about Schick ST3 Slim Triple Disposable Razors, Sensitive for Him, 8 ea:
Of all the disposable razors I've used, these seem to cause the least irritation and to last the longest (I can get two weeks or more on one blade). I've always had trouble around the neck, and while I still get the occasional knick, it's nothing like the all-out razor burn I get from other brands. Granted, it's no M3, but considering the cost of cartridges these days, it's the next best thing.
