Which Extender - AliExpress?

Hi,

Contemplating between these 2 extender kits:

https://a.aliex … ss.com/_msGkJsC
VS.
https://a.aliex … ss.com/_m0sdmSY

Might be difficult to determine. However, hoping for suggestions.

I also have the opportunity for the JES-EXTENDER, however, vacuum extending seems like the correct approach?

CHEERS!

they are both inexpensive enough where i’m not sure you can go wrong… under $7 for an extender, wow that’s cheap
