RRP is $27.99, sale prices ranges from $16-20, so this is a bargain if you don't mind the colour and you have Kogan First. They usually offer free trial for Kogan First so it's not hard to get free shipping.
I'm using the 700ml version of this and I think it's a great bottle for riding and keeping it chilled a little longer than a standard bottle. Just don't expect it to be like a thermal bottle.
