XPURC Glow Plug Igniter Nitro Engine Starter tool Apply to RC Car Support AA Batteries (blue)

whoever made this wasn't smart enough to test it first, engineered wrong there is threaded collar to hold the top half to the bottom battery compartment, to put it simply it doesn't work and amazon needs get rid of this seller.

Pile of trash the thing won't go on the glow plug half the time hard to explain don't buy it or buy it and find out.

Somewhat low grade

Doesn't work

I am happy with this purchase.

Wouldn't stay together

Died fast

Works great 👍
