Not bad but...
This is not a bad product. I have both the genuine 58 bottle & mug and this budget one.
I can safely say that the genuine one is a very good product but is very expensive.
The budget one is a good price but the lid on the bottle is a bit fiddly and sometimes you think it's on right but is not and then it leaks in your bag...
The genuine and budget mugs are the same I think.
If you have the money buy the genuine.
If you don't and don't mind the occasional leak then go for the budget.
