I just used the superspeed today for the first time. I believe it could be used as a daily shave. I usually go 2-3 days between shaves and the 34c does awesome for those days. I figure if I'm needing to shave everyday for an event or something, I can with the SS. Observations... My MTO doesn't cut for squat. The SS did nicely with one pass. The SS wasn't as "smooth" but the plating isn't as smooth or new either. And finally, the SS had a definite metallic scent... ?? Hmm. Over all, decent shave and mild enough for a daily shave. I believe I will accept this one into my "good to go" routine. I'll probably make a new post for the rest of the razors when I get around to trying them. I just wanted to post my findings.
Thanks. I've done some reading, but obviously not as up to speed yet. All of these have the Gillette stamp on them. I thought I had read that the goodwill had no logo. Any education on these would be great. SS Slim LC SC
