SousVideTools Senses 300 Chamber Vacuum Sealer | Sous Vide Sealer and Food Preservation System | Suitable for Dry, Moist, and Wet Foods | Commercial or Domestic Use | 30 cm Sealing Bar

The machine arrives with the heat sealing bar not fitted. It is in a polythene bag inside the vacuum chamber. The bar is simply lowered over the two round lugs at the front of the machine until they locate on the lower side of the sealing bar. AFAIK, you don't have to press down! I then used the auto "smart vac" feature and the machine worked perfectly. Obviously it's early days but this seems like a quality vacuum packer, and exactly what I expected.

A simple question from the user manual to there support department resulted in an unbelievable answer and still has not been answered. No problem with the product it does all I want but I don't like being given an unbelievable answer.

This product boasts an impressive speed when vacuum sealing and is effortless to clean.

Buy it and replace my damaged Anova vacuum chamber, I’m happy using it.

This item looks good. It pulls a strong vacuum. It would be simple to use. BUT. I had three of them and none of them worked. They all had to go back. I DO NOT recommend you buy this product.Firstly, the sealing bar did not get any more than even slightly warm on any of the units I had meaning that my bags did not get sealed.Secondly, one is supposed to be able to vary the level of the vacuum within the product bag by adjusting the amount of time the vacuum pump runs for. Unfortunately this failed to work on the units I had. Setting the vacuum pump for 1 second failed to stop the pump after one second meaning that the item inside would have gotten crushed when the chamber vacuum was released back to ambient pressure.I have had numerous vacuum packing machines over the years. This is the worst one I have tried.I had hoped it would work because, honestly, it looks pretty good and the build quality, the plastic moulding, the glass lid all seem good. But it was needed to seal bags and not look pretty on the shelf. So 1 star from here.
