Whenever looking at a piece I look at the most basic thing first. Where is the center of gravity? how big is the base? are my dumbass friends going to knock it over?
I ordered once from that place. I did receive the items in a timely manner. The quality of the product was very low. My advice is to find a local smoke shop in your area and get some instant gratification from your purchase. My last bong was plastic because I had ceramic flooring. A glass bong seems to work better and it's neat to see the smoke. Match your bowl with the size of the bong. Personally when I smoke a pipe I use the bong bowl on a chamber pipe. I find using a cheap rolling paper is still the best. Why do think the site is called Roll It UP?
the third one is the best of em, because of the double perc and its easier to clean than the #2 black leaf IMO, even tho its knarly, if its gonna be your daily and glass you use on the reg, get the #3, if your adding to your collection and want something cool looking and quality go #2, the first one is... alright...but thats me
I would go with #2 I've owned each style and I prefer 2... The first is a heavier pull the second is faster and the third can come in too hot depending on the amount of water it goes through
