I fish 4 to 5 days a week. So the crawler crib works very well for me. I fill it up with crawlers and go fish. I keep the c/c in an old fridge in my shop, the worms stay alive and fresh for the next day.
Not a bad product. Works good in early spring when temps are cooler. Late spring as temps warm, worms will overheat and get mushy unless you put them in a cooler. Make sure no water is in contact with crib as material will absorb moisture and worms will drown. I purchased two of them and have used them before. The Styrofoam containers keep worms longer but not as sturdy. I would recommend this crib with precautions.
