Review on Black Hydro Flask Insulated Water Bottle with Wide Mouth and Straw Lid for Sports by Mike Davan

I have 4 hydroflasks. I've been using straw nozzles on 3 of them for a long time. Mold has finally formed on my original straws (an error in the design of the original straw lids). I ordered these thinking it was the plastic mouthpiece version (to avoid mold). Neither of the two I bought work, they don't suck water. I've tried adjusting the angle of the mouthpiece, it doesn't help much, but there's still no full suction. Makes me think there isn't a good connection between the mouthpiece and the base. If this is indeed HydroFlask and not fake then I am very disappointed in them.
