Neat product, but doesn't last very long.
I bought two of these for my shop in Ohio. One for myself and one for an employee.
The advertised 1-3 hours of cooling is not my experience at all.
If it's 90 degrees or more in the shop, each ice pack only lasts 30 minutes, max, before having to replace.
That's not the worst thing in the world because each of the vest comes with 4 ice packs, but it's still nowhere near the 1-3 hours that they advertise.
This is with us filling the reservoir with ice cold water in addition to the ice pack, and leaving the vests in the refrigerator when not in use(we take the battery pack out first). Still only 20-30 mins before the ice pack is melted completely and the water temp starts to drop fast.
I don't know if it's a humidity thing, or condensation from the cold water in the vest, but when we take the vest off our shirts are soaked.
The build quality is ok, except for the zipper that feels very flimsy.
The small water pump, which is located in the lower back of the vest, gets very warm as well. The pump is covered by a very thin layer of fabric, which means you will feel the heat from the pump if it touches you, which it will.
All in all, its a great idea, and feels amazing when you put it on, but I expected more for the price.
Especially considering the 1-3 hours of cooling claim. I would not be here complaining if we got the advertised minimum 1 hour.
