We compared two men's 5-blade razor refill packs: the Gillette Fusion5 Razor Blade Refills (11 Count) and the by Amazon Men's 5-Blade Razor Refills (12 Pack).

What we looked at

Blade features, pack size, price per cartridge, and which handles they fit.

The verdict

If you use a Fusion5 razor and want a precision trimmer on the back of each cartridge, Gillette Fusion5 is the pick at £19.99 for 11, about £1.82 each. If you use a by Amazon handle and want 12 refills for £10.45, about £0.87 each, the by Amazon pack is the alternative.
