Pros :-Food stays more than warm (mild hot) for 5 hours.-Quality materials.-Easy to maintain.-Thermo seal is good.-We can carry two or three at a time, all the boxes are compatible with the rest.Cons:-Don't expect great heat from the lunch box, it's warm for 5 hours but ten times better than common hot boxes.-Should maintain with extra care.-As the metal is painted we need to scrub the lunch box with soft scrubber than steel scrub.Overall great dealThe design of it is simply the premium, the size is small with seperation of each is possible is its important benefit. I don't need food items in high quantity but the no. of items is more and with this i can place each separately and the the food is warm in the noon that makes me very happy with the tiffin box, its better to use three container box if you need more quantity in the noon.The box is pretty heavy and with already overloaded school bags this becomes an additional burden. My 13 year old was ok with the locking system which is really tight but my 11 year old found it a bit tough to open so stopped using it for him. Food stays warm though and totally leak proof so that’s a plus. It would be great for an office lunch box where weight is not much of an issue.I bought this product because i wanted a tiffin that looked trendy and also has the microwaveable option. I don't see this option much in other brands. I was happy that Vaya offered this option. Got this, so that if at all my kid or I cant eat our food on time and need to reheat it, it is efficient and functional in that aspect. The portions are apt for a quick meal. It is spill proof and easy to wash. The latch is easy to use and makes it safe for kids to open unlike our days where we had to bite/ seek help from adults to open our normal tiffin boxes. Loved the top handle feature for the portability. Kids will definitely find this easy to use. The camo colour is so out of the box and trendy. Special mention for the packaging that the tyffyn came in. The packaging box in itself looked good that i retained it too. The seller delivered the product within 2/3 days of ordering it! that was so prompt and quick! It was totally worthy to get a premium product from Vaya.Difficult to seal shut, difficult to open, difficult to place items, i feel they have downgraded their quality from the first gen tyffen. So honestly i am disappointed. The trays are made of some kind of coated plastic. Its not bad but just a little weird. Not sure i recommend this.
