This Iron Flask 40oz insulated water bottle was exactly what I was looking for. I work in public safety and am not always near the station to refill my water bottle and wanted something that would allow me a couple refills but keep the water cold until I needed it. This does exactly that. I used a 20oz shaker bottle as a water bottle, so this gives Iron Flask bottle gives me two refills until I need to fill it up again. It is the perfect size to keep on my passenger seat without taking up much room at all. I have not had any issues with the bottle leaking and it is very good quality. the bottle came with three different lids. One is just a standard lid that stays attached to the bottle when unscrewed and is stainless steel. There is a straw lid, with a silicone straw that goes into the bottle and a plastic straw on the plastic lid for drinking. The third is a plastic lid like a standard coffee thermal drinking lid. I have only used the stainless steel lid as I only use this to hold extra water to refill my other water bottle since I add a water flavor to it. All three lids have a handle source for easy carrying of the water bottle. I drop this thing all the time and it still holds up really well. Of course it is going to scratch or dent when you drop it, it isn't a magic water bottle. But it has not affected the lids or seals in any way. I like to put stickers on my metal water bottles anyways, so nothing a fun sticker cant cover up! I do not put hot liquids in this water bottle, so I cannot speak to how well it keeps liquids hot, but it keeps my water nice and cold so I wouldn't have any doubt in its ability to keep liquids warm for as long as it says. I would purchase more of this product in the future if I needed.

If I could give this bottle 6 stars, I would! It keeps my water ice cold for over 24 hours—even in a hot car—and hot drinks stay warm for hours too. The three lid options are genius: perfect for every activity from the gym to hiking. It’s completely leakproof, super sturdy, and the 40 oz size means I stay hydrated all day without constant refills. Stylish, functional, and built like a tank—this bottle goes everywhere with me. Total game changer!

Para ir al gym y en mi diario andar, los ml necesarios para rellenar sin andar con un garrafón cargando… y el mega plus para mi, es poder colgar mis llaves del auto en el gancho que tiene en la agarradera, así no las ando perdiendo en el gym
