SHEEFLY Stainless Steel Water Bottle with Straw-1 Litre Insulated Water Bottle, Leakproof Metal Water Bottle Double-Wall Vacuum Water Bottle for Kids Girls Boys Adults

Great 1 litre bottle to keep drinks warm or cold. Having 2 separate lids makes it extremely versatile for either sipping drinks i.e., cold drinks or having the wide spout for hot drinks. Tried it for protein powder shakes which I like cold and it kept the shake as if it had been in the fridge all day so would definitely recommend it. I've ordered the black bottle and have to say, it looks really stylish. With it being both hot and cold, means that I can just carry the one bottle and change my drinks accordingly. I have to say I think I have a bit of a flask fettish, I've just counted 20 in my cupboard. I've also just gone through them all filling them up with boiling water, then measuring the temperature after 3 hours then 8 hours. Sometimes flasks keep the drinks TOO hot to drink so I thought it would be useful to grade them. I'm pleased to say this flask came out on a par with my top three flasks. After 8 hours the water was still at 65 Celcius (drinkable) from about 80 degrees by the time I filled the flask. This could be further improved by preheating the flask first and filling it quickly (rather than faffing about filling 19 other flasks first!). The only negative I could say perhaps is that there is no pouring mechanism on the lid for hot drinks, you have to unscrew it completely, and no included cup. Not a big enough deal to lose a star though.

Ottima borraccia, veramente bella e ben fatta, la versione da me acquistata (950 ml) è GIGANTE, ma è quello che cercavo e non la trovo per nulla scomoda. Da l’idea di essere resistente, vedremo con il tempo come va. Terrò la recensione aggiornata per futuri aggiornamenti o commenti.

Perde acqua, la chiusura non è perfettamente ermetica, almeno per quel che riguarda il tappo con beccuccio. Credo che sia un difetto della filettatura del tappo che è in plastica. Mi è capitato anche che prendendo un colpo allo zaino il tappo saltasse via completamente causando un disastro.

If kept upright, this bottle is amazing. It keeps drinks cool and is easy to carry around with the strap on the lid. It also has a decent capacity. It would be perfect if it didn't leak/undo itself! I can tighten this to the max and I will come back to it and it is loose! This isn't great when it is stored on its side in my bag. I have on a number of occasions now opened my bag to have its contents swimming around. It is also too big to fit into standard cup holders.

Out the box, the product is nice, and feels good quality. I bought the 950ml size... With it, I got a flimsy (rather pointless) cleaning sponge, two spare plastic reusable straws and two styles of caps, a sipper and a sealed lid fitted with a finger carry strap. I wanted this for cycle rides but, (when full) it's way too heavy for mounting on a cycle bar with a bottle carrier... It's OK, it fitted in my bottle carrier, but on the journey it just bounced and twisted and got scratched to bits on a short 10 mile road ride. Probably better puting in a rucksack, but then as I said, it's heavy! Think the 500ml would have been better for me. Nevermind, looks great on my desk, apart from the scratches, they'll wear off in time I hope.
