Not at all. I went and looked at my unit and I have Model #V3840
Automatic Bag Detection
-- this is what takes the extra length of bag that is kind of a waste. You have to allow 3" to push into the unit. But...no more lifting the lid, inserting bag just right, closing and locking lid and holding a button down. It's all automatic and hands free. I'm used to it now and it doesn't bother me that much about the wasted bag , but it's something they need to improve upon in future models.
Retractable Accessory Hose
-- for your canisters and I love this feature of not having to keep the hose and attachment in a drawer, finding it and having to hook it up. Done now in a second and the hose reels back in to the unit.
Automatic Liquid Detection
-- senses food type and automatically adjusts seal level for a secure, reliable, air-tight seal. I actually experienced this first hand when I bagged some liquid. Afterwards you can tilt back the top of the unit and lift out the tray and empty it. No mess. There are also buttons on the unit to specify in advance what you are sealing.
-- Haven't tried this option yet but it may actually create a higher vacuum that usual since you are using a special container.
Vacuum Process Gauge
-- Displays vacuum progress visually and I think this is a cool feature. Its like a round gauge with red at the end when it seals and goes backward when finished.
Integrated Bag Opener
-- pops out from the bottom but I forget its there and have never tried it. I think it would be better higher up.
Two Speed Settings
-- for regular and gentle vacuuming needs. I use it for sealing loose flour and other items that don't need the strong suction. Nice option, plus you have the Seal Now button if you want to stop early.
Extra-Wide Sealing Strip
-- provides a better seal and the strip is longer for those gallon size bags. It says it will seal regular bags also (potato chip, pasta bags, etc) but I have not tried that yet.
Built-In Roll Holder w/Cutter
-- holds up to gallon size rolls and has a built-in slide cutter. Haven't gotten used to this yet since I never had that with my former units.
-- goes into standby mode when not used. Touching any button wakes it up. Since the unit is 'automatic' it does kind of stay on all the time, so if you make not like this if you are trying to cut back on power usage.
All in all I love it as I previously said, but it may not be a unit for everyone. If you want more control over where the bag seals, etc., you might be better off with the less automatic variety.
