Review on Kungfubull Infuser Tumbler Strainer Diffuser by Dana Bullock

Beautiful high quality glass bottle. The double wall construction allows for a cool green color while providing insulation and preventing sweating. Other than that, this bottle doesn't insulate nearly as well as a stainless steel vacuum bottle, but that's to be expected. In terms of insulation, it is on a par with a plastic-insulated Camelbak or Polar sports bottle. You'll also get some condensation on the bottle when filled with ice, but that's okay. The tea strainer is a nice bonus. It's a wide mouth, suitable for adding ice, although not as convenient to drink. The bottle is quite heavy and wide, not so convenient to drink and hold it. The lid is durable, high quality, will not leak.
