## Description

Review: Happy, happy, happy! - Excellent cup! Keeps drinks cold as well as any more expensive make. Came with two stainless steel straws and a brush to clean them. The straws tend to rattle a little when in the truck, so I opted to just use the seal tite closure on the lid while driving. The lid does screw in and it is leak proof when the closure is in place. The portion of the cup that sits in the cup holder is slightly larger in diameter than a yeti, so it may fit a little snug and not bottom out in the holder. Comfortable handle. All around, an excellent cup, certainly as good as any other and a little cheaper. Well packaged and fast delivery. Won't hesitate to buy another when needed.
Review: Highly Recommend these! - Honestly couldn't be happier!! I bought six of these (different sizes and colors) 5 years ago and they still look and work like they're brand new. No leaks, no rust, no chipping of the paint. And honestly, I like the lids on these a LOT better than my husband's Yeti cups of the same size. They keep things cold for a very long time and I just love them. HIGHLY recommend!!

### ⭐⭐⭐⭐⭐ Finally, a perfect replacement and upgrade for my favorite mug.
*by K***N on January 10, 2018*

I have been using the same 20-oz Aladdin mug I received as a Freshmen Orientation gift in college for the past 23 years. I have been somewhat nervous about my practice of drinking out of a mid-90's, frequently dishwashed plastic mug (most certainly NOT BPA free), but I never found a replacement mug I liked. I had tried using other metal mugs (the kind you get as freebies at conferences or sports events), but was frustrated by the sliders which trapped liquids and couldn't be cleaned (I drink homemade lattes daily, and trapped milk goes rancid before I even leave work for the day), and the mugs couldn't hold up in the dishwasher - a leak would always develop, usually in the base, and you could hear water sloshing around inside the "vacuum-sealed" mug. Additionally, these mugs were always 16 oz or smaller. I know that 4 oz doesn't seem like a lot, but I would always notice a difference when I ran out of coffee before I expected to. I decided it was time to find a replacement for my favorite mug. I wanted something dishwasher safe (that wouldn't develop a leak in the mug if washed and had a lid that was able to be easily fully disassembled and reassembled for thorough cleaning). It needed to be BPA-free, non-reactive (I use Essential Oils in my water, and would like to use them in my mug, which I couldn't do before, as they can react with plastic and aluminum, but are safe with stainless steel and glass), spill resistant (my Aladdin mug had open holes with no slider), insulated for hot and cold, fits in a standard automotive cup holder (my old mug was too big, but fit nicely into the center console of my mid-90's Outback (it's like they were MADE for each other!)) and had to hold 20 oz. The BEAST has fit the bill to a T. I have only had this mug for two days, and have only used the mug with the seal-able lid. My coffee stays hot until I have finished drinking it (which can be a few hours while I work at my desk). When my coffee is done, I can easily take everything apart and thoroughly rinse the mug and lid and refill with ice water with no lingering coffee flavor. I anticipate it will take a little to get used to drinking through a stainless steel straw, but I am VERY happy that this was included. A stainless steel straw will allow me to use this mug with essential oils, as I will be able to keep the oils away from the plastic lid by sipping through the non-reactive straw. An unexpected feature was the nose guard on the slider of the lid. I have had the experience with past mugs with sliders that, when I go to sip my beverage, the little tiny hole which is provided to allow air to enter the mug to replace the liquid coming out gets covered up and sealed by the tip of my nose as I drink, slowing or stopping the flow of the beverage through the drinking hole. This mug has a raised section which protects the air hole without preventing air from entering it. It is a little thing, but something I notice (with relief) every time I take a sip. The exterior of the mug is more compact than I expected, which is great. However, for some reason, it feels larger than it looks when I hold it. I have somewhat small hands (I wear Men's S or XS gloves/ Women's S or M depending on the style), and am finding myself holding the mug closer to the base for a better grip. I read the reviews from other customers and one of the tipping points for my decision to buy the BEAST was the customer service reputation from Greens Steel. I have received two emails from Greens Steel so far, checking in on my purchase to make sure I am satisfied and to let me know that they are available to help if I have any questions or encounter any issues with my mug. The reviews from the other customers make me feel like this concern and customer engagement is genuine and heartfelt, and as a result, I won't hesitate to get in touch with Greens Steel with any question I have, if necessary.
