Things to Consider Before Buying an Insulated Water Bottle


A water bottle is something you need every day, all the time. Hence, it should be able to bear the wear and tear of daily use. Most common insulated water bottles are made of 18/8 stainless steel.

These bottles are prone to dents forming on the surface when dropped. To ensure durability, try to prevent it from drops in the first place. A lot of companies have lifetime warranties on their products. You may seek those if you have dents or scratches or damages on just a few uses.
