*Completely Air tight (Seal is leak proof). *Sturdy Built Quality. Looks strong.
*The spring and the net inside the cap ensures that lumps are not formed. It seriously works very well unlike other shakers. *The bottom most compartment can hold upto one scoop (around 150 gms) of powder.
*****EDIT******* After almost 15 days of use.
*No Leakage whatsoever. *The bottom compartments actually hold slightly less than 2 scoops. But wont make much difference. It negligible.
Con: Cleaning the Cap can be a slightly difficult as there are many gaps and cavities in which the shake gets stuck.
-Just submerge it in water for 5-10 minutes and it will be cleaned. (Do not use hot water. I think it might change the shape and cap might not fit well after that)
