What is the difference?

[CurryLeafTreehugger]

I find 4 versions of the GB-187 on YinMing5's website and they all look exactly the same to me. Can anyone tell me what the heck the difference is between these 4 items?

For $32:

Also $29, but with a different model number than the one above:

WTHF? I can't see any difference between these. Can any of you?

#1 and #2 both have a straight sidecar mouthpiece, but #2 has a smaller/thinner body.


#3, #4 have similar sized body as #1, but with a curved mouthpiece

Dhgate sellers will often list the exact same item multiple times in their store

OK so is there a FUNCTIONAL difference at all between any of them? Would one of them be less prone to splashback? Is there a difference in function between the straight and curved mouthpieces?

 

[Simple10]

Very minimal difference in function but the sidecar mouthpiece in general does do a better job at preventing splashback.
