Polar opposite experience here. The seal between the bottle and cap is very poor and leaks - 4 different bottles, different batches, same issue. Would advise to steer away, unless you don't mind a leaky bottle.The SiS ones seem decent, I have a couple and they've not let me down.
Are you pushing the nozzle all the way home. The last ~1mm of travel has extra resistance as the seal closes, and it won't seal unless it goes all the way.Polar opposite experience here.

Previously I had a set of Zefal Magnums (the 2002 design) for about 15 years, but the nozzles never did seal properly when they were 'open', so the water came out of the side as well as the end, and all over my face unless I put the whole nozzle in my mouth and not just the tip.Zefal Magnum Bottle, Black, 975ml https://amzn.eu/d/emJm9x1
