Why people disagreed with her was because she said it smelled and tasted like real gin. It doesn't. No one but no one would think it does.
If the op had said, I'm pregnant, looking for an alternate drink, found seedlip, I love it, it doesn't taste anything like gin, and yes at 26 pounds it's very expensive but I'd thoroughly recommend as an alternative to any alcohol. Then fair enough, you do you.
Other alcohol free drinks, beer, wine, whatever actually taste a bit like, well, beer, wine, whatever. The point here is seedlip tastes as much like gin as orange squash tastes like wine.
It's marketed as a alcohol free gin alternative, and the price point is eye wateringly high once you remove the tax element, at least double the price of actual gin. And as such, it's a hugely expensive flavoured water to add to your mixers.
If anyone likes it and it works for them, that's beyond fine, but people are allowed to say either they don't like it, or it doesn't taste like gin, or simply don't wish to pay that much for a soft drink.
It's not personal to the op, unless she actually owns the company that makes it.
