Bought the bundle mainly to compare the three internal designs and they really do feel distinct in use. The bumps version has a firmer grip than I expected, which made cleanup easier too. Nice that all three come in one set instead of buying separately.

The three textures are noticeably different and the inner sleeves have held up fine after a couple months of washing. That said, cleaning and drying them takes longer than I expected, so I don't reach for them as often as I thought I would.
