At $60, this would feel like a swindle. I bought the Grifta for only $35 and almost got what I paid for. None the less, if you decide to pick up a Grifta Solo here is the link for the .bmp image you will need for Xpadder, as well as the controller configuration.
The Grifta Solo is a great concept; A one-handed controller that can offer the movement of a joystick paired with the accuracy of a mouse is the dream. While this comes close, the things it misses make it unreliable and a peripheral you'll come to forget.
Let's just get to the worst parts first so you can decide for yourself if these features will be a deal breaker.
Keep in mind this comes pretty bare bones, as in no instruction booklet or software CD. You get a brown cardboard box with the controller, a directional pad switch-out option that may accidentally pull a plastic interface off of your controller, and a few alternate bumpers that you will never use as space is already quite narrow.
The worst part of the Grifta Solo is the D-pad. We all remember the Xbox 360 directional pad and how mushy it was. The feeling of a flat circle on top of a toothpick is even worse here, as the D-pad is not much more than another joystick. It is fairly inaccurate due to this.
Also if custom controls are your thing, you better BYOS, Bring Your Own Software. The buttons are programmed to do what they show, but if you want to customize this thing at all, you'll need something like Xpadder or JoyToKey. And you will want button mapping software if you use your D-pad as you will find yourself hitting directions you did not intend to. I had to use a left-and-right prioritization for my D-pad to make sure I did not press the wrong button in the heat of a match. It's unreliable, and honestly quite frustrating.
The Start and Back buttons are... oh there they are, all the way on top, out of reach. Hope you didn't need to press the Back button to say look at a map, as it is just plain out of reach without shifting the controller in your hand. If you are not too worried about that it's not a deal breaker but certainly something you will notice if you do need it. The B and A buttons are not in my ideal location, but it may not bother others.
The built-in air mouse feature is plain bad. It moves around by itself when sitting still on the table. Absolutely turn off the air mouse feature immediately.
So you may be asking, what is good about the Grifta? Despite the flaws mentioned above, there were a couple things that did deliver. The thumbstick that is shaped like a thumbstick and not a D-pad works pretty well. It feels fluid and responsive. Taking a close look at the thumbstick in Xpadder, it has a fairly accurate center point and did not need any deadzone adjustments. It snaps back to near zero every time and no drifting. The only complaint here is that you reach 100% in any direction without having to bring the joystick as far as it goes. Basically, you only have to move the thumbstick about 70% of the way to reach maximum movement. It would be nice if 100% was closer to the outer ring on the thumbstick for more minutiae in movement.
Another pro for this controller is the layout for the trigger and bumper. The design is quite clever with the bumper being on the other side of your trigger finger. With small movements, you can hop between bumper and trigger easily and reliably. I would suggest keeping the smallest rubber insert on the trigger as space between the trigger and bumper is small, which is a good thing.
The Grifta gamepad is quite lightweight and the battery lasts. While there is no rumble, which is not a deal breaker for me, that helps extend the life of the controller without needing to charge. It never failed on me during my testing, some of which lasted a few hours and no charges in between play sessions.
Pass on the Grifta Solo. It pains me to say it, but this device is not up to the task of being a one-handed keyobard + thumbstick combo. I've tried a few different keyboard and thumbstick devices like the Razer Tartarus, but at the full price of $60 the Grifta is not worth it. If you are curious and can find this at $30, I would still think twice before buying it.
I really wanted this to be the controller that delivered, but it misses on a couple big features. If even just the Directional Pad worked better I might give this a Buy recommendation. But as the Back and Start buttons are too far to be usable, the D-Pad is a spinning plate, and zero software support, it is not a great replacement for the keyboard.
