I think I’ll buy them to review the material while doing some sports…might be useful for the first 30minuts (and then just relax…) - it’s hard to read books even on fitness machines.
I used them for L2. They were nice to have but I wouldn’t say they helped me pass. They are word-for-word readings of the Notes without the examples. They were good for commuting. Not sure if they were worth the price tag.
