The barrel is turned using a cog which “grips” a rubber ring on the outside of the barrel. Ours was very prone to slippage and it is essential that this whole of the outer barrel is 100% dry before setting up.
The cover is a bit fiddly to put into place, but not a big deal really – the switch is depressed by a prong on the lid cover itself, we had to press down quite hard to get this into the slot and connect with the switch.
Again, only one barrel – MUST BE KEPT SPOTLESS!
The shape of this barrel, whilst its a good size and extremely robust, means that grit can accumulate around the lid parts. Not something to deter a buyer, but bear in mind that cleaning is a little more difficult as you have to get something like your finger bent round beneath the lid – whereas on straight moulded types its just a case of a wipe around the top. See the image on the left to look at what we mean.
