I purchased a short swivel tube for my Nuance Pro from an Amazon seller and I received different part than I’m used to. The fit is fine but instead of being the standard tubing, it’s the “lab version.” It’s opaque white and much more rigid and slightly shorter but stretches pretty easily.
Does anyone know if there’s a durability difference or any other reason I shouldn’t look for a refund? I’m not sure if I got something better or something worse than the normal tube. I would assume lab tubing is designed for single use, but I really don’t know and can’t seem to find any information on it.
