Anyone Else Using Multibit?

Is anyone else using this service to act as a medium between your purchase source and the end source? Have been using it for well over a year, however until recently it seems that my transactions are taking days to finalize whereas before it was merely minutes. Is anyone else having this issue?

never heard of it

What do you use as a separate source for your bitcoins? For example: I buy through coinbase and transfer to my multibit account. From there I have a few wallets which I pull from to use as payment.
