The straw lid it came with however is why I gave it a low rating. The mouth piece is already ripped after only a few days of use and needs to be replaced.EDIT: after the company read that the lid had failed, they shipped a replacement. Awesome! ### ⭐⭐⭐⭐ close to perfect *by S***Y on October 30, 2017* the good. I like the size. Didn't want something too big or heavy but needed a bottle big enough to make the commute to work. I like the finger loop and the straw works well. Also, it was oddly hard to find a flip top lid that didn't cost a fortune. (I definitely didn't want anything that required two hands.)the not-so-good. It says it keeps beverages cold for 24 hours but i find that my ice melts over night. Water stays cool-ish but not cold. This is just around the house so I'm doubtful that it would keep it cold for more than a couple of hours in the heat. (I haven't tried hot beverages.) ### ⭐ The straw top is useless and does not work *by C***M on December 11, 2017* This bottle is defective. The straw top is useless and does not work. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/70204242-smart-flask-wide-mouth-stainless-steel-water-bottle-18-oz](https://www.desertcart.tn/products/70204242-smart-flask-wide-mouth-stainless-steel-water-bottle-18-oz) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-30*
