Review on 🔒 3M 00051131173583 Versaflo Standard Capacity by Mark Greenwood

So you're paying over $70 for half a backpack - this item looks more like a prop than a backpack as the blower unit is strapped to a prop and there's no real storage compartment, and even more multiple compartments. That means you'll have to pay over $30 more for the rubber "adapter" if you want to use it with the TR600/800, for a total cost of over $100. For less than half that price you can buy a real backpack with many more features (including charger and USB port). But since it is "Health Care" it will have a maximum markup.
