I have been using Food Savers for 30 years. Been happy with the results but salmon does start to turn after a few months. Beef seems to last much longer. Never a problem with broken seals or punctured bags. Just be carful about what you put in. The place I fish in SE-AK vacuum packs and freezes your fish every day. The bags are much heavier than the food saver ones. We had a chunk of halibut tonight that was caught in 2014. Was still pretty good. I don't normally let it sit around that long. Salmon hits the smoker after just a few months.
