We've reviewed a lot of different mobile controllers over the years, and if you looked at the selection that we've featured, then you'd definitely notice a pattern or two. Most of them are in sleek black and most of them are horizontal stretch-to-fit. The Riot PWL ESL mobile controller isn't either of these. It's a white, yellow and green controller with an attachable, central holder that extends vertically, to snap around a phone or tablet in landscape view.
There was a point where this design was in fashion, and, at that point, the Riot PWL ESL probably wouldn't have stood out alongside the headlining competitors beyond its bold colour scheme. However, there are a few extra features on the controller which, complete with the (now) less commonplace design, really make it into an interesting package.
If you're not using the controller then it's totally fine to leave the mount in - although it's certainly not as compact an offering when left like that. And, when you travel you can leave it in a bag or pocket. But, it just seems like a bit of an unnecessary faff. The strange thing is that the mount actually extends long enough to clip over the back of the controller, but due to the always-connected cable it can't sit steady. The cable is, of course, integral to the design, and so can't be changed, but maybe future revisions will have slight changes to the mount shape so that it can clip on the back; that would be a welcome improvement.
The mount is very smart though. I like the clean branding, and the small plastic cover on the controller (which makes a yellow bar when pushed in, and is easy to remove) looks sleek. It, alongside the yellow analogue bases, d-pad, triggers and bumpers, serve as a really sharp accent on the otherwise white-front, green-back controller. It's also got a ridge along the top of it where you can rest the cable, shorten it and keep it in place when using the controller with a phone, it's still a bit lumpy, but better than it could have been.
Obviously, the controller layout is great. But, notably, there's a headphone and passthrough lighting port on it, meaning you can charge and listen to audio at the same time. The lighting port (to phone-tablet) is hard-fitted onto the controller, which does mean that you'll often find that it's a bit too long or short at times, depending on whether you're sitting back from a tablet or using the mount.
I do like the idea of the fitted lightning cable, but it does restrict the phone to modern iOS devices. This is an effect of the 'Wired Connection is faster' mentality that dominated eSports a while back, and if that tiny fraction of a second is important to you then this is a great controller optimised exactly for you.
Because that's the thing, you can buy a mount for about £10, and you can mount that onto an Xbox or Playstation controller. You'll get the same great shoulder buttons and triggers (and they really are great on the Riot PWL ESL), but miss out on the Share button feature, pass-through charging and that millisecond latency fix.
One thing that is worth stressing though, that I've not mentioned yet, is that RiotPWR controllers are apparently the only Apple MFi certified controllers that have clickable thumbsticks (L3/R3). I've not tinkered with many other controllers in the classic, console form and so certainly can't verify that; however, the clicking of the sticks and the feel of the triggers feel great.
The Riot PWL ESL mobile controller is a premium controller with a well-designed mount; it occupies exactly the same price range as its main competitor, but if ESL branding or fractionally-faster inputs are important to you then this is the one for you and an easy choice at that.
