Tumbler Double Wall Steel

Actually works! Feels sturdy in hand & comes in nice packaging. Holds more than my last stainless steel insulated shaker. Keeps drinks cold. The watertight drinking opening feels effective when opening & closing & its easy to drink from. Easy to clean due to not having something extra rattling about inside. Not had any problems with clumping of workout powders. I’ve never tried it with soft fruit. My shakes however are perfectly blended. The only thing I don’t really like is that the handle doesn’t feel that durable. Other than that I give this shaker a 10/10 as it seems very durable. The handle seeming to me as a possible weak point. Maybe that’s an unfair assessment as I haven’t had it that long but I do love it & hope none of it fails as I plan to use it for a long time.

I believe there is an issue with the cap. The opening does not close completely, which causes leakage, particularly when the bottle is shaken. I previously had a plastic version that worked perfectly, but the metal one does not function properly.

Excellent build quality, solid, no leaks and most importantly mixes my protein! Couldn't be more happier. Hopefully will last a long time 🤞🏽
