A little late to the party here, but Bubblebagdude is far from a dude, the bloke is a cock.
I have used their bags a few times, and as per the previous comments they fall apart rather quickly - the last purchase from them were the all mesh - they arrived in clear film wrapping, so the postman had a good old nosey as to the content! I mailed them and they said Amazon pack it so its up to them...if you value secrecy avoid them completely.
Back on topic, I have since bought a set of all mesh 'hashtag ya hashbag' 5 gallon set, they are well built, and take the amount I out through them with ease - good sewing all round - and a touch cheaper just to make them even nicer
