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)

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)

🟢 looks nice 🟢 Leak proof lid 🟢 Closes with a flipping lid which is much better than the sliding ones you can't clean properly 🟢 Lid screws on 🟢 Holds heat perfectly 🟢 Good size 🟢 Smooth to sip from 🟢 Rubber part on the cup is removable ℹ️ Do not microwave ℹ️ Hand wash only

I was going to send this back as the lip is quite sharp and makes drinking a little bit awkward. However since using it I’ve found it’s actually a great little cup purely because it’s so leakproof. Great for travel, the flip cap means you can take it in a rucksack side pocket and enjoy a hot drink a couple of hours later. Recently took it on a three hour journey and it was still nicely warm at the other end. For this reason I’ll keep it and give it 4 stars.

I recently purchased the CS COSDDI Travel Mug (380 ml, Black-A) and it has become my go-to coffee cup for every outing. Whether I’m heading to the office or embarking on a road trip, this insulated mug delivers outstanding performance and convenience. Pros: ✅ Excellent Temperature Retention: My hot coffee stays steaming for up to 6 hours, and iced drinks remain refreshingly cold, making it perfect for any season. ✅ Leakproof Design: The BPA-free, screw-on lid with a silicone seal ensures that no spills occur—even when the mug is tossed into my bag. ✅ Durable & Hygienic: Constructed with double-layer stainless steel, this mug is both sturdy and odor-resistant. The detachable lid makes cleaning a breeze. ✅ Ideal Capacity & Lightweight: With a 380 ml capacity and a feather-light design, it’s just the right size for daily use, whether at home, in the car, or on the go. ✅ Sleek & Timeless Look: The powder matte finish gives the mug a modern, stylish appearance, making it a great gift for family and friends. Cons: ❌ Limited Color Options: I would have loved a few more color choices, but the Black-A option is elegant and versatile. Final Verdict: The CS COSDDI Travel Mug is a reliable, well-designed cup that keeps beverages at their ideal temperature and prevents messy spills. It’s perfect for daily commuters and travelers alike. I highly recommend it for its performance, durability, and chic design!

When I first ordered these, I was a bit unsure because some reviews said they weren’t leakproof. On my first use, I actually thought the same… until I realised I hadn’t properly secured the lid! 🤦🏼‍♀️ Once I closed it correctly, I had no issues at all. I bought this mainly to take on holiday for my coffee, and it did exactly what I needed it to do. It’s really easy to use and feels well made. The insulation is impressive — it keeps drinks hot for hours. I left mine for over 5 hours and it was still warm enough to drink, which I wasn’t expecting. I’ve had no leaks since using it properly, so just make sure the lid is fully closed. Overall, I’m really happy with it and would definitely buy again.

Brilliant 👏

Brought partner one, he boasting how great his was as he is bus driver. I brought one for myself. Does exactly what it should keeps coffee hot for bout 2hrs. You hold and carry the cup without burning your hand. Outside stays cold and keeps coffee hot.

It leaks and hot drink is stone cold after 2 hours wouldn't recommend

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

This coffee thermos is great. Not only does it look nice, but it keeps coffee hot, and is easy to clean. It’s pricey, but worth it in my opinion.

ممتاز

Excelente calidad de Vaso, no se derrama, permanece caliente durante mucho tiempo, también lo útil es la base anti-derrapante.

This product was quite disappointing. Two main reasons: 1. Finish is poor, used it twice and already the label is fading out (wondering if this was a genuine product) 2. Heat retention is very poor. This was the main reason for my purchase and it doesn't even last 45 minutes Haven't spotted any leakage yet, so i suppose that aspect works Overall wouldn't recommend it
