I've only used the round containers of wipes, but was looking for something that was easier to carry on my travels. I tried these on a 2-week road trip and was very pleased. Each of the formulations of wipes in tubs that I've used have different smells, so these are no different to get used to. But that's just evident during the cleaning. They are moist with just enough liquid to clean and dry quickly. I also tested them on my skin and there was absolutely no sensitivity nor lingering smell. My mask sealed well for the night and there was no residue that I noticed. I like that they are also partitioned into smaller quantities and fit nicely in my CPAP bag. I can carry just the number that I need on my trip and the bag seals back very well for the number of times I opened it (I only use one a day in-between washings).
If you travel a lot, these wipes are perfect. A box has 12 packs, with each pack containing 10 wipes. I keep 2 packs in my CPAP case. The wipes are odorless and fast drying. Very convenient!
