### ⭐⭐⭐⭐⭐ Great value for money
*by L***O on 9 August 2026*

I’m insanely impressed with this bottle. I’ve been using it for a little over 3 weeks now, and I can say it’s durable, leak-proof and keeps my water cold for well over 12 hours! The straw / lid options is great, it’s a huge size and the colour is adorable! It’s helped me keep up with my water intake as it keeps my water super cold all day. I will definitely be getting a smaller version for my office days!
