Pros:
- It works well and has no trouble with mylar. The 4.5 mil/side (9 mil total for two sides) bags I’ve used need about 7 seconds heating time. The unit allows up to 9.9 seconds.
- It seems to be well-built and if anything, overbuilt. The lid is thick acylic-type plastic, so the entire bag can be seen during the sealing process. The vacuum chamber is stainless steel vacuum and is solid. Welds have been ground smooth for a good seal with the lid.
- I like that the sealer is in the back, making it easier to load bags than if the sealer was in the front.
- Individual controls for vacuum time, sealing time and cooling time conveniently avoid menus. Not clear in the literature: you can push and hold any time button and the time setting will progressively increment or decrement until the desired time is reached.
Cons:
- It’s large and heavy, weighing about 60 lb. It’s not easily moved if you use it in one place (i.e. kitchen) but store it in another.
- The tray insert has finger holes, but they aren’t deburred, so they’re sharp. That’s easily fixed with a small file.
- The switch is mounted to and protrudes from the side of the unit. It would be better if it was recessed to avoid damage while moving the unit.
- The heated sealing bar jumps upward to press tightly against bags when vacuum is reached. The movement causes bags inside to shift. I put wood blocks behind my bags to hold them still.
- It’s somewhat noisy while the vacuum pump is running.
- The bail flips up, but is not designed to flop down on its own while the lid is being closed. Be careful not to force the lid closed while the bail is up!
- My unit stopped working after sealing 4 or 5 bags, but started working again later. I assume the unit has a thermal switch which overheated and tripped while the vacuum pump was breaking in. After 30-40 bags, that hasn’t happened again.
