I have multiple Cheeki products now and they are honestly the best! I live in a really hot climate and the insulated drink bottle keeps my water cold all day. I also just tried the new tri-tech sports lid and it's so handy to use this when I am running to ‘drink on the go'. All the products are completely leak proof and I usually hand wash them, but it’s really convenient to be able to put them in the dishwasher if I need to. The 350ml insulated coffee cup is also amazing and I just purchased another one for my partner. I have tried so many other ('good quality' brand) insulated thermos mugs/cups to take my coffee to work/hiking etc and all of them have let me down in some way (leaking, doesn’t keep liquid warm, too big etc). I have never had my Cheeki cup leak in my bag, even when it has been shoved in the middle of my hiking pack, and the size is perfect to take when traveling (I keep this in my handbag now when I am on holiday to have a reusable cup with me all the time). I can’t recommend these products enough and it’s nice to be able to support a local Australian company too.
