Ocean BottleBig 1l | Stainless Steel Water Bottle | Reusable & Sustainable | Keeps Drinks Cold & Hot | Eco Friendly Gift (Obsidian Black)

A bit pricey but worth it. Keeps everything cold or hot for ages; no leaks. The dual opening is excellent as it means the bottle can actually be cleaned properly

Have been using this everyday since it has been delivered - mainly for getting my daily water intake at home, or taking it with me to work/gym. I opted for the larger 1L bottle to be on the safe side.For the time I've used it, its been great. The Ocean Bottle keeps my drinks cold during the day, and my hot drinks nice and warm when out and about. I have not tested the temperature over longer periods of time (i.e +4 hours), so cannot comment on paramount longevity of the drink remaining at the desired temp - but from there description, they are not trying to compete with a proper thermo bottle. So it all depends on your needs if this suits what you want. In fact the website itself advises 'The lid is deliberately not insulated, to avoid drinks staying too hot for too long (you do actually want to drink that coffee, after all) and to keep the bottle lightweight.'One of the main reasons I purchased this was to be able to give it a really good clean at the end of each day. You can split the bottle from the top third, and easily get a large cleaning tool inside. I have not tried this in a dishwasher, and probably wont as it's easy enough to clean in the sink. If you really want to scrub every nook and cranny, you can also remove the inner seals inside the lid and top portion, then place back in when dry.Really happy with this purchase, so much that I have just ordered the 500ml version, mainly because the larger one does not fit in my car holder (not a fault of the product, each car varies). So I can then have different sizes for shorter trips when needed.

The large cap means it can be filled and cleaned easily. Super durable as well

Leaking after just a few months of light use. Has been well looked after and not put in dishwasher. Very unhappy given the cost.

Had it for a couple of months and it was fine but after a while I started to get a really terrible plastic taste from the water. I tried to wash it so many times but to no avail. Chucked it in the bin not long after.

Plastic top gives off an unpleasant smell despite being washed, sterilised, steeped etc. Doesn't keep drinks cool for very long and ice has normally melted within an hour. Disappointed given the price and there seems to be better, cheaper alternatives out there.

Purchased and started leaking straight away, really disappointed!

The seal in the middle of the bottle has stopped working less than a year after purchase, meaning you can't lift the bottle to take a drink without it leaking on you. Company only offers a 30 day refund which is ridiculous.
