In short, there are several issues with this controller, I'll summarize the pro's and con's, feel free to read my detailed review below.Pros:- Saturn form factor, D-pad, and 6 button layout is still one of the greatest of all time.- Overall feels great in hand and great to play with- Construction feels solid.- 2.4ghz connection feels good and responsive with no notable latency.Cons:- Instruction manual is incorrect, and refers to functions/procedures that do no pertain to this product.- Analog sticks have short range of motion, huge deadzones, and snap to cardinal directions rather than smooth analog movements.- No analog triggers.- C & Z buttons are hardwired to L & R, with no way to change button layout, or assignment of any buttons.- PC dongle was troublesome to sync at first.- USB-C port does not allow for wired connection, requires 2 USB ports to charge and play simultaneously.- Upon release Saturn users reported numerous bugs.After waiting 5 years for this controller, hoping it would suffice as a universal controller for both modern retro games, I have to say controller product is a disappointment. There is a hole in the market for a controller that has the following:- 6 face buttons (classic layout for many fighters)- A great d-pad- Two analog sticks (needed for all modern games)- 2 shoulder buttons- 2 analog triggers- 2 or more function buttons, (home, select, etc. required for modern games)For some reason there is no legitimate controllers that offer these features. There are other controllers such as Hori Ex2 turbo controller that does have this layout, but has a S#!tty d-pad, its also discontinued. The only other such controller I have found with these features is an Aliexpress knock off of 8bitdo's m30 with full sized analog sticks, but a misaligned button layout. I've also tried much more expensive options like the Victrix pro BFG, with the fight pad attachment, but it also had a few quirks that disqualified it from being my main fighter pad.Retrobit teased a saturn controller with modern features as far back as 2018, the prototype showed full size analog sticks and analog triggers, after 5 years of R&D there is no excuse to have such a poorly executed release of such a highly anticipated product.This controller has several glaring issues:1. Analog sticks: In testing, when attempting smooth rotation they are jittery, and have very coarse rotational control, as they snap to cardinal directions as other reviewers have expressed. The analog sticks also have huge dead zones. They may have hall sensors, but they are poorly designed compared to similar non-hall sensor sticks you'll find on the switch. They are serviceable, I've played some 3d games that had 1st person shooter elements to test (Last of US, Black Ops I zombies) The games controlled fine, and were playable, but small adjustments were notably difficult to make even compared to Nintendo switch analog sticks.2. The shoulder buttons L & R have been made a much thinner to accommodate the new chassis with the added LZ and RZ buttons. It would have been better if they made the top of the controller slightly wider to allow for all shoulder shoulder buttons to be in a more ergonomic position. As a result your fingers rest on the LZ and RZ buttons, rather than L & R. The LZ and RZ buttons are in a comfortable position, but are digital inputs, not analog triggers like they should have been.3. The face buttons C & Z are hardwired to mirror the L & R buttons. This oversight make not only makes it impossible to replicate the Sega Saturn button layout during emulation, but also makes alternate optimal button layouts for fighters also impossible. Normally an issue of button mappings are a issue that can be addressed through firmware updates or support software, but Retrobit has confirmed that the buttons are hardwired together and alternate button mappings will not be possible. This to me falls into the category of false advertising as this controller was marketed as a controller with 6 face buttons functional buttons, and 4 shoulder, which would have been 10 function buttons, but you effectively end up with 8. Further more in D-input mode there is a upper limit of 128 different buttons, so there is no excuse to not allow for all inputs to be used independently of each other.4. Even though the controller has a USB-C port, it functions solely as charging port and does not allow for plug and play connection. This means you need to use 2 ports (one to charge, one for the dongle) to use the controller while charging. Again, in 2024 "plug and play" is a feature that should be a standard, but Retro-bit seems to think that a lack of a wired mode somehow can be marketed as a feature. I suspect the reason retro bit has intentionally programed their firmware this way is because when the non-replaceable battery eventually dies, the user will be forced to purchase another controller rather than continue to use the product. Very apple-ish planned obsolesce. Every other controller, including my 8-bitdo 2.4ghz M30 allows for a wired connection. As someone who sometimes plays competitively, I generally prefer to go wired for the most stable and lowest latency possible.5. some people complain about the top row of buttons being a different shape/size compared to all the same shape and size. This is how the original Sega controllers were since the genesis/megadrive so I don't count it as a design flaw, BUT when Sega originally released the saturn saturn analog pad, Sega changed all 6 face buttons to the same size, so I do see having the face buttons to the same size being further improvement to a modern Sega Saturn styled controller.Most of the issues with this product were requested by numerous posters on their twitter prior to release, so Retrobit should have been well aware that releasing this controller without the following features would result in a eventual negative or lukewarm response from the target demographic. But its obvious that Retrobit underestimated the potential market for this controller outside of Saturn hardware users. The original they prototype was much better, but then Retrobit presents a new "prototype" and then claimed the changes in the design were "improvements", but they were not. It's obvious they skimped out things like better analog sticks and analog triggers to cut down on cost, but I know myself and others would have gladly paid more money to have a fully featured modern styled saturn styled controller.Hopefully 8-Bitdo or another company will execute this concept correctly.
