Looks solid, didn't notice anything soldered weird. Direct replacement. Fits great. I wish it would have been a bit cheaper. Would have scored six stars if it had south facing LED's.
This updated board can replace your old CTRL or be inserted into a CTRL case (standard or high profile). I added a CTRL foam kit to mine, resulting in what comes with the V2 keyboards. The many new LED effects are a nice addition. Just wish the board was a little less expensive.
Board came with left alt socket not working, but still good for my use, so it prevents me from alt tabbing when im mashing keys while gaming and suddenly find that im in another screen (fortunate accident) Drop was kind to send a replacement unit to me (not sure how that turns out as it has not arrived yet.)
I decided to upgrade my ctrl v1 because I was trying to use it with signalrgb software and was having trouble finding firmware that worked reliably.

Upon receiving the new pcb, I was happy to see that pcb mount stabilizer holes had been added (one of my main gripes with the ctrl v1 was the stabs) , so I threw on a set and promptly discovered that the top frame of the v1 keyboard was not compatible with pcb mount stabs.
A few minutes with a dremel in strategic spots solved that issue.
I found a suitable firmware compatible with the v2 ctrl and signalrgb and it works well with qmk or signalrgb. The stock fn keys still do their thing too.
I am happy overall, as without noisy stabs this now makes a nice backup keeb. I am currently using it at work.
