Not the easiest to connect the lid, it's gotta be "just right" or the tabs either won't click or will unclick (mine have unclicked while in the fridge, ruining the contents" NOT FOR PEOPLE WHO NEED SPEED & EFFICIENT but a good dishwasher safe product, seal and lid don't warp in the heat. If you put the extra second into putting the lid on, it works really well. Not for people trying to multitask and only use one hand!
