Here we go again. Crickets are fine. However, they should come from a reputable source that offers healthy crickets. ONce you receive them you should offer them leafy greens, dry dog food, veggies, etc to ensure they are getting a healthy diet. When I need them I buy them by the hundreds and keep them in a rubbermaid tub with a bed of dry oatmeal as a substrate. They get a shallow dish with a sponge for water. If you do it right they are great feeders.
