CS COSDDI Travel Mugs, Insulated Cup With Leakproof Lid - Reusable Travel Mug - Car Cup - Stainless Steel Mug for Hot and Cold Coffee, Water and Tea (Black-A, 380 ml)

I’ve had this now for 2 years and it’s one of the best I’ve brought from Amazon. It really does keep your drink really cold or really hot. Like when I have coffee in it it’s still hot for more than 4 hours. I would have to take the lid off for it to actually cool down. Good size and it doesn’t spill so you can just chuck it in your bag.

Great little travel mug. Keeps my drink warm for plenty of time (before I drink it all). Is a nice shape and size making it easy to hold and is a good build quality. The lid is also very easy to take off while still being leak proof which I’m a big fan off Easily drank out of unlike other travel mugs I’ve tried and doesn’t leave any metallic taste in my drink (after a wash of course). (Picture with Amazon fire tv remote for size reference of the 380ml size)

Firstly the colour was very important to me so in really glad it's teal as I hoped. I've taken pics with different objects to help you see it clearly. I'd describe it as a dark tealy blue (although we all see the blue/green divide differently) The lip of the cup has a little glob of excess sealant on it (photographed) that means I have to close it extra hard - I'll trim it off and it should be fine. With lid and screw top firmly closed it's watertight and I can hold it upside down without leakage. Cup feels sturdy. Corrugated grippy sleeve is removable and the tiny gaps above and below are actually just the edges of the inset middle of the cup designed to keep the sleeve on, so they're not difficult to clean crevices. Unfortunately the sleeve has moved around more than I'd like as I've had this first drink, tending to slip down slightly, so I've been pushing it back up a bit. Perhaps the top needs stretching to match the widening angle of the cup, or perhaps it wouldn't move if the cup were more indented where the sleeve goes, allowing the sleeve to sit fully flush and not be tempted to creep out of position. The base says "Do not microwave" and "Hand wash only" This is my first reusable travel cup thing and I was surprised by how the lid gets in the way of my nose. Maybe that's normal, although it could be solved by having the spout raised higher and/or the lid set lower, so that the open lid wouldn't have to be flush with the spout I'm drinking from it - noses famously tend to stick out further than lips 😅 If I could change anything, I'd also make the flip lid click close even tighter. It's pretty good, but the thought of it getting hooked on something and opening in my bag has me wanting to give it it's own pocket. Maybe the little net pockets outside my rucksack will become cup holders. Happy with my purchase. The colour makes me feel good. It holds like a mug and a half of drink, but is still comfy for my small hands and wont weigh me down.

Great travel cup and keeps hot for a few hours. Using one of these cups for a few months now and bought a second one in different colour whilst on offer. Easy to clean, durable and good quality. I don’t wash in dishwasher so perhaps that’s why it’s still as good as new.

It’s perfect for daily commuters and travelers alike. I highly recommend it for its performance, durability, and chic design!

Going to cut it short because that is the only thing that matters: No, it doesn't leak. Watch the video for demonstration, I used orange juice. Just make sure you close it probably. 2 years of using and everyday I'm just impressed it doesn't leak lol But it will definitely spills if the small lid came in contact with something that will left it up so beware. you can't just throw it in your bag, but for sure it won't leak if closed. Even though it says don't shake it, I do shake it because sometimes the coffee needs some mixing, so as long as I'm holding the top lid firmly then it is fine. The non-slip bottom is life saving, and the silicon sleeve does indeed do it is job, and I wash it every day and nothing got damaged or anything so far after 2 years of using it. The material is firm and nice, looks expensive and IS solid. It does blows you away to be honest. Buy it if you are not aggressive and wont be expecting it to be your punch bag. Honesty, some of these reviews makes you so confused: these cups are to be used, and as you use them more, they will worn out, they aren't supposed to last forever. But also, if you gonna bang them ofc they are gonna be scratched and damaged. Just be normal while using them.

I chose the pink with the view that my husband wouldn’t steal it! 30 minutes after making a drink in this cup, I’m still waiting for it to cool down enough to drink it! It certainly keeps things hot and doesn’t leak - so far

Fantastic mug, have had it a few months now and use it all the time!! wether it's for my coffee sat in the garden, or keeping my drink cold during this hot weather! absolutely love it! Keep drinks hot or cold for a good while! Bought my husband one too. Very sturdy but lightweight. Brill! :)

Buona tazza termica, tiene il calore per almeno 4 ore! Ben fatta!

Nettoyage avant première utilisation : la couleur a déteint donc d’un beau bleu, j’ai une brasse plein de taches blanchâtre avant même la première utilisation! Elle est trop grande pour passer sous ma machine à café : je dois donc utiliser une tasse classique et transvaser , très pratique ! En conclusion et vu le prix , très mauvais rapport qualité/prix

Ottimo acquisto. Facile da pulire e tiene benissimo la temperatura. Non gocciola!

Tazza perfetta che mi salva ogni mattina 😂 mantiene caffè caldo per tanto tempo! E le bibite fredde idem. Consiglio perché dopo tanti mesi di uso continuo è ancora nelle perfette condizioni.

This is a quality product. It fits perfectly in the car and doesn’t spill in my desk. It keeps drinks hot and cold. Washes well and lasts.
