KLEIN TOOLS 55580 Stainless Steel Tumbler with Flip-top Lid, Insulated 20 oz. Tradesman's Double Wall Vacuum Mug, Slip-Resistant Sleeve

I don’t work in construction but I do work in healthcare as an NHS junior doctor and most doctors don’t always get a chance to get a full cup of hot tea or coffee when they’re busy. After trying various thermal mugs I had heard about the Klein tools mug and I’m glad that I got one. Keeps my drink hot for ages! I was so impressed I’ve got four more to give as gifts for Christmas. They’re pricey at £35-40 but I’m looking at it as an investment as opposed to money wasted. So far not had any problems or issues with leaks, they’re easy to clean and they keep a hot drink hot/warm for at least 6 hours. Just what the doctor ordered.

The best vacuum mug you can get ;) It keeps your tea etc hot. The best part is the magnet. Once attatched that's it(the mug being full)

Very robust, strong magnetic, not working very good in the fridge... But any other metal is great

Keeps hot for ages, never tried to keep anything cool yet but my guess is it would do a good job, made a coffee at 6AM , kept the lid closed and opened it at 14:00 took a sip and burnt my mouth

Good cup but doesn’t fit cup holder on car

Expensive for a thermal mug however the magnet is a great feature and it actually does keep the drink hot for 4 hours at least

Excellent product heavy duty and just brilliant

I use and love my new work cup ,

Tough,great size and perfect my husband loves it stays cold for hours worth the money hard to dent or mess up. Great for an electrician

Excelente copo. Robustez e eficiência no que se propõe. Além de bem acabado e ergonômico. 10x0 nós copinhos da moda.

Love it love it love it, nothing else to say

Excelente vaso la verdad que me gustó mucho, hecho de muy buen material la verdad quedé más que satisfecho.

Keeps my coffee warm for about 5-6 hours and hasn't leak yet and I had this cup for about 5 months now
