So you cant run this wide open airflow you have to use one of their included pins, and even the largest one is quite restrictive. Also the wick holes are on the bottom, thats normally fine but theyre on the bottom of a flat square base which sits flush against the bottom of a flat square boro tank... so even with the tiny little channels they used that are supposed to alleviate this issue do not. It wicks like shit and wven if you drill out the wick holes it still wont wick because of the location of the holes. Point being i wouldnt have bought this if anywhere on the desceiption it said MTL only.

Excellent workmanship, everything you need is included.
The only thing I would like is a larger selection of Air Pin.

I normally use a 1.2mm airflow in most tanks/bridges but the 1.2mm airflow that comes preinstalled in the Molen bridge only has small intake holes in the bottom of the airflow pin so it makes 1.2mm tighter than usual. My preference is wide open airflow in base and 1.2mm under the coil, I find this is perfect for MTL. Besides that though it's a great bridge for flavour and I will keep using it.

Overall, this is a pretty decent bridge. Building and wicking are both straightforward, and the performance is quite good. Very nice machining and fit/finish. For the price it would be hard to find another bridge that performs better. I also like that it comes in a plastic case with cutouts to hold all the parts (adapter and airflow pins) to help keep things organized.

Swapping the airflow pins is an easy, tool-free process. Just be sure to transfer the insulator ring to the new pin! It's an easy part to overlook or lose, and a spare is not provided in the spares pouch. I find the 3mm pin works well for me (RDL) so I won't be doing a lot of swapping.

It does need an adapter so it can be put on a mod for resistance checking/pulsing coils. You have to remove a retaining ring (threads off; no tools needed) before putting on the adapter. More often than not, removing the ring loosens up the airflow pin. It's a functional design, but not nearly as convenient as some other bridges.

It's a capable bridge for the price, and a good starting point if you're just getting into bridges.
