So far, i've been using the gUSH and VIV ones for more than a year and no breakages yet.
The thicker and more uniform the glass the better... some of the cheaper generic ones i previously ordered online had relatively thin glass walls and inconsistent wall thickness, they would break even when i just do simple cleaning with a soft pipe brush (always at the sections with the thinnest glass), so even if one was very careful, the lower quality pipes will still have a much higher chance of breaking.
Its definitely worth physically checking each glass lily pipe closely to make sure it has thick and uniform glass walls, they are all handmade items so even within the same brand and batch of glassware i still find differences in the individual pieces. Avoid pieces which have uneven glass texture or hairline stress cracks, only get the best ones from the batch on display.
I guess that's one of the pitfalls when ordering glassware online, you cannot inspect it beforehand so its all about luck that you get a good one.
