Pros: 1. Great built quality 2. Nice colours it scheme. 3. Attractive looks 4. Good chamber system for storage facility for protein and pills, etc. as reserve. 5. Decently priced but could have been cheaper.
1. Has a design flaw...the pills chamber should have been a separate one and not meant to be kept inside the shaker compartment or either of the two attachable compartments. It would have been better if it was a separate chamber. Sure, the height of the fully attached shaker would have been more but at least there would have been a more convenient option. Otherwise, as right now the pills cap that which can't be kept in the shaker with moisture after initial use, has to be kept with the powder chamber and that renders the chamber unable to screw tight into the bottom of the shaker. Hence, the chamber needs to be emptied to make room for the pills chamber.
2. The shaker of this brand is available (same design and material) on amzn itself for a cheaper price by another brand.
Rest everything is cool , the built quality of the shaker is very good and overall a good purchase.
