I researched this product online and came back to redber because it offered the best price for this item. I love glass mugs anyway and struggle to find one that I feel comfortable drinking from (slight OCD) this mug is perfect and feels balanced. Does not conduct the heat from the drink straight out into the Atmosphere.. The strainer is great and with larger leaf tea is perfect. I bought fine tea leaves. Some of which go through the holes but I'm happy with that as I always leave a dreg of tea I'm my mug. Overall a great buy and fast safe secure delivery. Highly recommended to others.
