I have used quite a few of the other products in the range and have found that the hamsters like them but i have not tried the 'crunchy tuber mix'.
Mine have had the dari nibble cobs, mixed dairy drops, rodent marbles, wellness gnaw stone and carrot woodroll with out any problems.
They were not very impressed with the rodent marbles but that is because they are horrifcally spoilt and know if they beg long enough they will get something better.
