Thanks for the links guys. It would be great if they posted pics of the inside filler etc. I just examined the two types I have
1st batch: The filler is around the sides and there is a plastic tube in the middle with a little metal hook thing coming out the centre. These are the ones I really liked and found east to fill etc.
2nd batch: These also have the filler around the sides, but have some weird spiral plastic in the middle with no metal hook thingy. These are horrible and tend to lose flavor quickly. I also find these much harder to fill.
Any ideas on how I know which ones I am ordering. so confused lol
