Bought a tub of this soap on a whim today. It cost £2.19 in our local Lloyds Pharmacy, but can be had online for under 2 quid.
I thought it would be hopeless, but it's marvellous, a complete bargain. Sure, the tub is cheap plastic, but the soap is great. It smells brilliant, old barber shop type smell, clean and fresh, doesn't last long enough for me. Very easy to lather using my cheap Kent bristle brush, it was foaming all over within seconds.
I did buy a Kent soap in a wooden bowl at the same time as that's what I was actually after trying, and only picked up the Erasmic to try as it was so cheap. Not really feeling an urge to open the box of Kent now. :)
Give it a try if you haven't already, I'm stunned at what it gives you for pocket change.
