I wouldn't & I so desperately want to try the choc mint ones.

It's not the actual soft serve that is the concern, but the cleanliness of the pipes it goes through in the machine. My concern would be that the crushers is made in a similar type machine so there is milk going through pipes as well & the risk of listeria is increased if the pipes are not immaculately cleaned. You also have the concern of not knowing how long the milk has been sitting in the dispenser & it's kept at the right temperature at all times.
