I own this bubbler, and it's my favorite of my new Chinese acquisitions.
My piece is really well made, all the welds are good, I found no bubbles in the glass and there is only one small scratch near the base. Keep in mind quality varies from piece to piece though.
I got it in transparent (I requested this in the order's comment, but I might have been lucky).
I use it mainly with my Solo, and I keep the water level at the bottom of the honeycomb disk (initially with a little air bubble trapped under the HC).
While clearing it there is nearly no restriction and the bubbles stack well without water hitting my mouth.
While pulling through the Solo, the restriction seems to only come from the Solo itself.
Regarding Sunshinestore versus Kathy, I got an order from SS in a total of 4 days, but it was when he add no cheap shipping options for outside of the US, so it was shipped Express.
With Kathy it took 4 weeks from ordering it to having it in my hands, but shipping was free and that's a time I'm used to when ordering things from China with free shipping.
Kathy did took a few more days to process the order though (about 4-5 days while I got a tracking number the day after I placed the order with SS).
Also I updated my signature with the pieces I now own. I think most have been covered before, but if anyone has a question regarding one of them, feel free to ask.
Edit: I have
this honeycomb ashcatcher, not sure if it's the same as the one from SS, but while it hits well (I use it mainly with a J-Hook, still haven't tried it attached to a bubbler), I definitely enjoy the inline to HC bubbler more.
Edit 2: also check
this and the few posts that follow, there should be a few comments about this piece.
