BLACK + BLUMTravel Cup - 18/8 Stainless Steel Thermal Insulated Travel Coffee Cup with Leak Proof, Lockable Lid - Keeps Hot for 4 hrs, Cold for 8 hrs, Slate - 340ml

Looks good, is completely leak proof and mostly works as advertised. Two main issues I have with it is that it doesn't keep your drink hot, merely "warm" for around 3-4 hours assuming a room temp of about 20C. The other issue I'd found with it is the rubber base pad is ineffective to the point of useless as it is too thin to actually make contact with the surface you are putting it on, and therefore doesn't reduce noise or provide any kind of grip to avoid it sliding.Other than that, it's a little overpriced, but will probably last a long time.

I’ve yet to come across a Black + Blum product that wasn’t excellent quality and value for money. So easy to disassemble the lid and clean thoroughly. I love using this product. It keeps drinks hot for the promised 5 hours. Highly recommend this product.

I use this daily so I get to drink a hot coffee while chasing 2 kids about. Super safe thanks to locking mechanism and the design of the spout means less likely to spill when drinking too. Way easier to properly clean than my last cup of similar price. I like it so much I have I have just bought another as a gift.

I'm always buying hot drinks at the station, so thought about money-saving options. This is a really good insulated drinks flask. It kept my latte warm, even though I sipped it 2 hours later. Easy to open and close. Cleaning was not a problem and loved the fact I could dismantle the led clips to give it a thorough clean.

Nice design, leak proof but doesn't keep drinks hot for long. Warm only after a couple of hours unopened. Not sure I like the drinking hole either.
