Review on Personna EasyFit 3 Mach3 Razor Handle Compatible Refill Cartridges –15 Count & Blades - Compatible Mach3 Handles by Theresa Brown

I don't know how anyone uses it! Many people have written positive reviews so they must have pens made differently than mine. I have a Mach 3 Turbo grip that I bought in March 2019. The problem in any case is that the cartridges don't snap at the handle, just expecting the friction in the joint to hold the blade! My hilt doesn't have retaining tabs that connect to anything on the blade, but Gillette blades have little notches that connect to the lugs on my hilt. Run the blade over your skin and it slides off the handle. I've also tried Target brand cartridges and they seem identical to these and they don't attach properly either. I spent money twice!
