You need to clarify which model this is. They have 2 nearly identical. The ONLY way to tell is dimensions. One is 5.2 x 23.7 x 10.2 inches (GameSaver Big Game Plus) and the other is 8.5 x 21.5 x 3.5 in ( GameSaver Big Game GM710) The GameSaver Big Game Plus has bad reviews even on the FoodSaver web site.
It looks like the GameSaver Big Game Plus with the red switch.
check the model number in the spec section and the look at the model number on the Amazon link
Like all Food Saver models, this one is excellent at sealing. I have the older game saver model, and it has functioned perfectly for years now (at least 8).
