The lids seem to be a little loose. Is this by design?

The lids have a gauge on them. The temp is supposed to be right in the middle. If the lid spins easily, the temp is about right. If it does not spin, it is too cold and if it sputters steam it is too hot. So it is loose by design.

The largest container's lid closes tightly on our set, as secure as the smaller containers. I just got off my lazy butt and double-checked. So I'd say you have a legitimate complaint. BTW, we love our set. We love how it stacks together so slimly, and would heartily recommend it to others - as long as the lid to the largest container fit as well as our does.

The lids fit snug. The dividers are deep. As far as leak proof, I'm not sure what you plan on doing with them. If closed and left upright I don't see them leaking.

Mine fits snugly. I do notice that if the bottom screen, etc., is not tightly screwed to the lid stem, it isn't as tight a fit, so you might try checking that. If that doesn't work, I would return it as defective.

Not Snug is actually a little better. there was an issue with the original MagnaLite Professional lids (Yes I own a set) and they would tend to seal themselves with moisture. this (I have read) had caused a couple of lids to "blow off" the pot. Also, the lid was designed that any steam that hit the lid would funnel back down to the inside lip and back into the food. The fact that the lid is not very snug is a good thing IMOHP...

I have not had any issues. I've even put them in the dishwasher and the lids still fit snug.

The lids are slightly loose, but I love the shape of these dishes and use them constantly. The lids are tight enough for storage purposes, but if holding liquid and tipped sideways, you might have a leak on your hands.

Sometimes the seal can be a bit loose. Once it came off and stuck to the plastic lid. Have you looked inside to check?

Yes, the lid is tight fitting. Everything stays in its place. It's a great organizer.

I didn't have any problem with the lids not staying on. I ran my finger and thumb around the lid's edge and onto the container and it snapped into place. Hope that's helpful.

The lids seem to be of good quality yes. I haven't used them a whole lot thus far but they have been great the few times I've used them.

No. The lids are thin metal that loosely fit on glass jar. The glass is very nice, thick, heavy. The lids are the opposite.

Yes, it's intended to be a little loose. That appears to just be part of the design. The top on mine does not fit tightly into the glass beeker whether the plunger is up or down.

I cannot remember if ours did or not; might be normal. Sometimes just a little bit of wiggle room allows you to close the lid gently and adjust to fit onto the bottom section. Just a thought.

Well, the lids are secure, but at the same time, they lift off easily. I suppose that a screw-on lid would be MORE airtight, but I have not had a problem maintaining freshness in these jars.

There is a soft rubber seal around the lid which if tightened ought to prevent moisture getting in/out. I have not tested this however, it is just m impression from inspecting the container.

Mine are pretty snug. I made mini flans and the lids keep the caramel in nicely. No problems at all.
