I got the two D020s I ordered in recently. They were so nice paired with my LSV I didn't wanna give either to a friend for Christmas (I break glass often, and a luxury once sampled becomes necessity.) Ordered them with one lot of J hooks from the same guy, they were standard thickness, high build quality (basically just meaning all the same size/shape with j-hooks.) My order went really smooth, and I still wanted to give some of these things away, so I bought two more along with one of those 14mm shower-head ACs, and a 5 pack of the 14male to 18male adapters (great for the LSV.) I will say that the weld on my D020 can where the stem attaches could be smoother on both, but both are strong and fully functional. The percs on both of mine are identical and low, but from some of the pictures it seems some of the silts come a little higher. The package came so full of bubble wrap I had to give it a twice over to make sure I got everything out. Some of the products on their shop in DHgate have pictures of a Chinese glass shop (I guess it their shop?) that looks pretty cool to work at actually, lol. Overall, pretty friggin happy with this DHgate bubbler deal, it is now my daily driver and receiving many droopy eyes stares and slowly articulated compliments.
Also, the oil rig it comes with isn't the worst either. It has a little glass cup, which is infinitely better at frying my entire than the flat-head designs that were the norm the last time I owned a glass nail.
