The Sinnsally costs £11.89 and is rated 4.3 stars from 1,336 ratings, with 1400ml of capacity in two stackable tiers.\n\nIt takes sixth because the two-tier design is genuinely useful and the sample is the second-deepest here, while its microwave claim excludes the lid in a note at the end of the bullet.
