Review on 🥤 Sip Straw Lid Pack with 2 Lids, 4 Straws, and 2 Brushes for Wide Mouth Water Bottles - Vacuum Insulated by Spliff Sinha

Grooves on the lid are very tight and not sure they will fit a 24oz thermos perfectly. The straw has round cuts on both ends instead of oblique cuts on one end to extract the maximum amount of water. Thermoflask's original tube has a slanted cut at the bottom so it sucks water from the bottom of the bottle where the round cut doesn't. must keep the original pipe. It is good that the kit comes with a brush to clean the whistle. Very helpful. Pros: Cleaning brush Cons: Closes/opens very tight to the 24 oz thermos I got from Cost. The manufacturer's product on the left in the photo is inferior in quality and finish to the original Thermoflask cap on the right.
