I used them once. While they were a great soap, I can't say I thought they were great for the price a bar of it goes for. So, if the price point doesn't push you away from them, I did not encounter anything that I would call a downside past the cost.
I quite like the soap, but I think there are better ones around for what it now costs here in the UK, or considerably less. I was a more regular user of the Musgo Real shaving cream, but there again the cost has increased so much I prefer to buy others. It's a good shaving cream, but just not that good.
