Which gives a closer shave, the Mach3 or Harry's Plus?

Harry's Plus has five blades at progressive heights and a 45-degree pivoting head, which generally shaves closer with less drag. The Mach3's three blades are fine for daily shaving but less close.

Which is cheaper over a year?

The Mach3 starts at $8.99 and its refills are widely discounted, so it usually costs less overall. Harry's Plus cartridges last longer per blade but cost more and are sold mainly through Harry's.

Can I use Harry's blades on the Mach3 handle?

No. Mach3 refills fit all Mach3 handles, and Harry's Plus cartridges fit only Harry's Plus handles. The two systems are not interchangeable.

Is the Harry's Plus set worth the extra money?

If you want a metal handle, five blades and a kit with gel and a travel cover, yes. If you just want a cheap razor with easy refills, the Mach3 at $8.99 is the better value.

How long does each cartridge last?

Gillette rates the Mach3 at up to 15 comfortable shaves per refill. Harry's rates its Plus cartridges at up to 21 shaves.

Which is better for travel?

The Harry's Plus set includes a travel cover to protect the blades, which the Mach3 does not. Both are small enough to pack easily.
