This mic helps me to make the online kids feel like they are part of our in person class. It all of the sudden gets very quiet. Why these are called slippers, I do not know. I fell in love with this product over 20 years ago when I found a small 3 ounce bottle in the local half price store. I just need to get one for my husband next! When I did they were concerned about the stripe I had across my foot. Didnt feed as fast as I would have liked. I was torn between the midform and the platform, and I do not regret my choice at all, because the midform is so easy to walk in. Would have appreciated if they didnt do that. You also need add an accessory collar to adjust the height of the tray while on the stand.
