No. They're my favourite too. I prefer Minstrels though. The same, only bigger and just plain brown. "They melt in your mouth, not in your hands."
Don't know if you get them in the US, but the chocolate is actually chocolate, not the US chocolate-flavored sugar crapfest so favored by Herseys et al. Hershey's Kisses? More like Hershey's 'pour pure sugar down my throat, babe'. Ack. I'd heard of these when living in the UK and was looking forward to trying them when I first visited the US. I now know why they don't market them in the UK. Chocolate vs American chocolate is the same is a meal vs Pot Noodle.
Maybe that's why I could tolerate plain M&M's in the US. They were so small that the shell/volume ratio was such that you couldn't really tell how bad the chocolate was.
Update: Minstrels are milk chocolate buttons with a hard glazed shell sold in several countries including the UK, Ireland, South Africa, Cyprus, and Spain. The brand replaced the similar Chocolate Treets.
They originally had the slogan "They melt in your mouth, not in your hands", the same one used by M&M's in the United States (also used to market M&M's in the UK in the 1980s and 1990s).
In line with Mars' re-branding, Minstrels have been repackaged and are now sold as "Galaxy Minstrels", referring to the use of Galaxy chocolate in them.
