The Caliber 3 is available in Boots, Superdrug and Morrison's.The Caliber 5 is available in Boots, Superdrug and Asda. The GT5 is only available in Tesco, this is sold in Japan as the Schick Quattro 5. The GT6 is only available in Australia at Aldi.
All of the Caliber and GT carts fit the Quattro handle. The Caliber 5 Core Motion Technology handle is available in Germany from Balea and in France by Wilkinson Sword as a Quattro Titanium. This is Edgewell's version of the Flexball. QShave sell it on AliExpress.
The EasyFit3 is available at Tesco, Wilko and Asda. It fits it own handle which resembles the Matrix or the Gillette Mach3. It uses an adapter similar to the Hydro Connect. Remove this and it's a Hydro cart. In fact the cart is the Hydro3 mk1.
Thanks Sabre - 'er indoors had me on a Tesco grocery run this morning, I saw the GT5 which sells as Tesco Pro Formula For Men Diamond 5 Blade........................ if I'm not mistaken.
All de and Fusion razors will cause me irritation when I get the least bit careless with them. My most comfortable shaves come from genuine Gillette, Mach3, cartridges. I have been able to pick them off of ebay for about $1.10 ea. Combined with a Razorpit that makes the Mach3 system pretty affordable.
Best regards - Ron
I think the MR3 has the nicest handle of F-System range, its a shame Feather have discontinued these & the blades. The F3 (Samrai Edge) are a good replacement but not the same as the MR3.
