Review on 🍺 Mr. Beer Homebrewing 2 Gallon Deluxe Beer Bottling System with 0.5-Liter Bottles: Complete Your Brewing Experience! by Lauren Walton

Some reviews say there is no difference between cheaper conventional cylinders and an oxygen barrier. Traditional cylinders are made of thinner plastic, similar to a water bottle. The O2 is thin enough to be compressed by forced carbonation, but definitely more durable. You can see how much easier it is to see through the regular bottle on the left. While the thinner bottles could handle 30psi for a forced draft carb, I can't use my vacuum bottle filler with them so I need to find someone who can use them. (Coopers can handle my vacuum bottle filler without breaking down).
