I got the new fluxos in the mail the other day with the clear silicone cup and they do not have the middle o ring in them. I always throw the cup part away and flip the black o ring over and use that. The new fluxos do not have the o ring in them for me to use. Is this an oversite on the ones I ordered or are they just not coming with them anymore. I wanted to just order the conversion kits and not worry about it, but I have not been able to find them on the website. Do they plan on selling them again and if so do you have any kind of time frame on getting them in stock. I apprecaite any help you can give. Thanks in advance.
