Review on ☕️ Enhanced Focus and Caffeine Kick: Scientific Glass Caffeine Beaker Mug (400mL) by Nathan Vaughn

You get what you pay for. I bought this to replace another similar mug I bought from Amazon which was more expensive. What I received was different from the photo you see on this website. I have uploaded a photo of the mug I received. I checked the caption and the caption is completely inaccurate. What is advertised as 80ml is actually 50ml. Also, this mug feels much poorer in quality. It also has an unclean yellowish tint which leads me to believe it's not pure borosilicate glass like the other mug I had. Don't buy it unless you want a cheap knockoff of the more expensive borosilicate glass mug you can find on Amazon.
