Review: Exactly What I Was Looking For - 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.
Review: Be careful it will dent!! but overall a great price and great cup overall! - Great price, keeps it very cold for days!!!, and great size. It might not be your typical brand but it works just as great! Do be careful, although it’s a great cup and keeps everything cold af, it will dent if you don’t take care of it properly or if u drop it really hard. I lost one cup at worked, dented another pretty bad, but 3rd times a charm.

This is the 2nd time purchasing this product. After 2 years I lost the 1st one but can tell you this product is extremely well-made, keeps ice overnight and liquids nice and cold. Never chipped, color never faded, and the cap and straws remained intact. Would recommend to all.
