Twist Edge Leaking

I bought a Twisp edge a week ago for a whopping R800 with no liquid included which firstly is a complete ripoff. but I spent the money hoping this is a long lasting device with more expensive materials used in the manufacture. <br> But it seems this is a really flawed design. From the first time I used it the liquid leaks up into my mouth while I'm using it and I have to clean it out every 10mins. which never happened in the previous version I owned. This is unacceptable at that price. Also the way its been made is really counterintuitive. <br> <br>
