I have to say that anyone who owns a Lenovo Yoga C740 15.6 inch with 12GB RAM should look elsewhere for a Bluetooth compatible pen. This is only useful in a simple context. If you just want to use something for basic navigation to avoid screen smudges, this can be used. But even in those aspects you can find it jittery/flaky at times. Not particularly good at scrolling either. After all, it comes down to one thing: why do you need it? If it's a feature-rich task and/or quick and quick navigation, then it's not for this laptop. I can't comment on the functionality of other suggested items to use this with, but these were my findings with my laptop's current specs.
