My authentic Nautilus I put away, missing the pin in the spring (was it ever even in there?). Authentic coils I have had fail.
Poor mans Nautilus? I tried a "clone" Nautilus for around $11 and "clone" BVC coils for $3 per 5. Except the clone did have the pin in the spring (that's what made me realize it was missing from the authentic) there was no difference. It's been about 8 months and have not had a single coil fail prematurely.
After the first test I stocked up on both the "clone" tank and coils.
I often wonder if they are really clones...
Yeah I've been tempted by the eBay clone Nautilus but already had the BDC. The coils are exactly the same thing and perform the same. I learned to rebuild the non Nautilus coils from a Nautilus rebuild video. Only difference is the Nautilus offers AFC and larger capacity tank. And back in the day the BDCs were like a third the price of a Nautilus.
As for the clone coils? I doubt it also. Factory seconds is more believable to me.
