Hi mums, I'm expecting twins in Feb and have purchased a TT Maxi tub on eBay. Now, the seller assures me that there are no parts missing, however there is no little knob to turn the cartridge round as there is in all the smaller models. So, from what I can see it actually doesn't work properly, and in essence it's just a bin in which I may as well just use a bin bag (which completely defeats the object!) So, does anyone have one of these they have used to tell me I'm not going mad and there is something obvious I'm missing? I've contacted TT directly and they can't advise me on instructions or spare parts as they have discontinued the model.
TIA x
