I'm sure it'll be the standard way of drawing in the future.
A vented design to equalize pressure seems such an obviously good idea too I can't believe it's not standard or even easily available in the US. Seems the silicone seal in the Amazon one can be easily blown out when pushing air into the vial causing leaks as mentioned above.
You can see how quick a vented spike draws and no messing around with air as it equalizes automatically.

You do provide the forum with some valuable information and insights. Granted. However, one needs a gargantuan joint to tolerate your bullshit. Chill man.....
