This review is from: As Seen On TV Debbie Meyer Bread Bags (Equivalent to 120 bags)
Whilst I haven't run a side by side test with 2 home baked loaves and I don't tend to keep them that long these bags have kept my bread fresh for up to 4 days - could have been longer but I'd eaten it by then. From experience home baked bread can get stale before that, within 2 days. So, yes they seem to work, very inexpensive and re-usable.
