JBJ vs inline glass bubble counter

So whats the pro and cons for both? I was told the inline glass bubble counter is more accurate and less likely to ruin my regulator if it fails. As for the JBJ, I was told that the integerated check valve(made by China) will eventually fail and I can say bye to my post body.

Inline glass bubble counter:

Advantages:
Will not flood your regulator setup (as long as you use a good inline check valve)
Some prefer this aesthetically
Relatively cheap

Disadvantages:
Must be mounted/stuck with suction cups to something
Fragile
Can be a hassle to clean

JBJ style bubble counter:

Advantages:
Can be mounted directly to regulator setup
Comes in chrome plated brass, brass, aluminum
Not as fragile as some of the cheaper glass bubble counters

Disadvantages:
Can leak back (you must use a quality 1/8" NPT check valve)
More expensive
If overtightened, the plastic can crack

Hope this helps,

Anthony

I like the glass ones. There's no moving parts, and they look very clean, though the bubble size is much smaller, so don't try to compare the two bc's that way.

I swore off the JBJ-styles. The check valve will fail, probably in under a year (less than 6 months for all of 5 or 6 that I've used), and the plastic cylinder cracked on two of them. Also, they tended to leak for me, specifically at the threaded connection at the bottom.

You can run a decent check valve before the bc to help keep fluid out of the rig.
