"Advantages of these over Lock & Lock" star star star star star This review is for an older version of this product I have not noticed the problem of the seal not releasing when the box comes out of the freezer but then I would usually thaw out in advance. However, for me the best thing about these boxes (apart from the fact that their "locks" appear very sturdy and strong) is that they are HYGIENIC. With lock & lock, after use you need to keep taking out the seals, washing and drying them and the location where they sit - unless you want to find to your disgust (as I did one day) black mould under the seal. This are much easier to manage - a definite plus for me :-)
"Problem with freezing" star star star star star_border I also found that I was unable to remove the lid straight away after the box has been frozen, so I'll probably also have to wait a few minutes when it comes time to defrost and use the contents. I'm relatively new to Clean Click, and this is the first problem I've had with one of their products. As long as it doesn't damage the box, waiting a few minutes to remove the lid after it's been in the freezer is something I can live with, but the problem should be preventable.
"no comparison" star star_border star_border star_border star_border These containers are not comparable to your original LOCK & LOCK. The seal on your new ones freeze up when in freezer. You have to stand and wait for up to five minutes for the seal to defrost. support_agent A note from the team Thanks for taking the time to write your review, I'm sorry that you'd been disappointed with the boxes, I'll be in touch shortly.
