Pros:- 100 percent genuine imported product with documentation and packing. Absolutely solid mount, the phone will not jump out even if you do a bit of motocross riding, go through potholes and even do a few jumps, much better than the xgrip for rough use. The XL size fits my large S9 plus perfectly. Does not hit any buttons as you can customize where the Lclamps bolt on to the base. Simple to assemble and can be done in a few minutes, be careful of the small screws supplied and do not lose them. Tighten the self locking nuts well. Can buy a spare base and use on 2 motorcycles, the spare costs around 1000 bucks. Cons:- Expensive piece of kit by any standards. Might spoil phone cameras, this is an issue very few people have faced, so I'm taking the chance. Should supply spare Lclamps, they are plastic and are difficult to replace if broken or lost.
