PCE Bolt together converter (pictures)

I bought this converter for $675.00
After I opened it and saw inside, i thought to return it.
The company gave me an RMA to send it back.
Thoughts?
Cheers!

 

How is that unit sealed? It seems like it should have a big O-ring.

 

If you like/need to constantly adjust the way the converter works to help tune how your car goes down the track these can be good. As long as you have the big selection of parts to swap in and out. If you don't and won't not sure its an advantage

 

interesting there was a seal in the box..but not installed in the converter..yikes!

 

I’d keep it and play with it just to try and learn how a converter operates and what to do to change the characteristics of it.
Those things are amazing inside
