Review title: Mehh, does not really work, cheap plastic insides
Product review: The extender looks good on the outside, but the threading inside the extender is a plastic insert (too weak to hold a seal or hold on the bike over time) so if you Teflon tape and then try & really snug it down the treads will pop in the extender, thus making a bad seal and something that will likely fall off later. You want an extender with a machined thread, not a cheapo plastic insert.
