They look very similar, the only difference being the tops on mine are all rubber/plastic and NOT a metal point where the centre hole is. Not sure that makes much difference though. Thanks
hi @BigAl good luck with these. I bought some and didn't get on well with them, they gurgled n dribbled and didn't respond well to the poke up with tissue. I might have been doing something wrong of course. Would like to know how you get on so I can re-try mine please :-)
Hi @Hilary. Merry Christmas to you as well. A couple of mine do gurgle a little, but I can live with that, but had no dribbling from them. I get a decent amount of vapour and an ample throat hit. So I'm more than happy with the bosses choice
