Pros: Works good when it does

Cons: - Onboard video chipset overheating issues (Dell is aware of this and only extends an extra year warranty for this problem)

Other Thoughts: We have had over 70% of these D630 with onboard video chipset overheating issues at work. Of the remaining 30% or so its probably just a matter of time before they start acting up. Don't waist your money on this laptop unless the issue has been addressed. And even at $230 your not really getting a good price, this is a very old laptop.

Pros: Inexpensive when on sale
Last a long time
Water sealed (no leakage)
Easy to clean

Cons: One clip broke after we tried to open it right after we took it out of the freezer. So if you use them to freeze something I would recomend that you wait a bit before unclipping. Despite having one broken clip it still seals good with 3 out of 4 though.

Other Thoughts: I bought 2 sets of these last year and so far I have been very pleased with them. I meant to give one set as a gift but kept them all for me hehe!

The seals are easy to take out with a small groove that allows you to take a butter knife to take it out easily without damaging them. The containers are easy to clean and after a year of usage they still look like new (unlike so many others I've used)
Just did a test last night by putting some water in it and then shaking it upside down and no water came out, thats after using them for almost a year so the seals seem very durable.
Overall I am very pleased with my purchase and wouldn't hesitate to recommend them.
