most AC folks really oppose the sealer -
a few problems - many garages recover and reuse the refrigerant - the sealer can contaminate their system so some will refuse to touch a car if you tell them or they notice it. Some will even test for it. It can also obstruct the expansion valve and small passages in the condensor / evaporator.
It does work for some people. I imaging those products do get better with time, too.
My neighbor tried it in his 325 and it didn't work, and the dealer insisted he had to replace every component in the AC loop. He traded the vehicle in for $0.50 on the dollar instead. Whether he was conned or not is up to you decide, but that is the risk.
I would only put sealer in a system if I was so broke that it was that or no AC at all, and I wasn't concerned how the loss of the AC would reduce trade-in or resale value... And thankfully I haven't been that broke in a long time ;-)
