Having joined Slimming World and immediately feeling the need for naughty foods, I wanted a tool to measure out sweetie syns. This is fab. I worked out what syns the portions are and can swap between different sweets so you don't feel as though you miss out. For the price it's a really good piece of kit (for a toy), and I may buy more as they're pretty fun and my grown up kids like them too. Buying bulk sweeties on Amazon is a big help as well.
