"A worthless dispenser. Your old dispensers peeled off the address label from the tape for easy placement on envelopes. Why would you bother to place three slots on the new dispenser when one would actually have worked as it does nothing but hold the roll. Thankfully, I saved my old dispenser and will use it....throwing this new worthless one away. Recommend your retool your new dispenser to peel away the l.abel from the paper tape"
