## Questions & Answers

**Q: How bright are these lights at night? I have had problems with previous mouses shining into my eyes when the lights are off.**
A: The light is electric blue and is not overly bright, in my opinion. I'm sure the light being emitted from the monitor at night will be much brighter than the light from this or other MICE.

**Q: What is the expected battery life on a single charge? i also don't see a mouse driver program on j-tech's website unlike the other mice they sell.**
A: Depends on usage. I use mine daily as I do online school at home. I only have to charge mine maybe every 2 to 3 weeks. The light will stop working first. I still get about another week after that before I have to charge it.

**Q: Hi! love this mouse except that the scroll button seems stiff and sticky..only been using it a day and wondering if it will loosen up in time?**
A: Mine loosened so much that it often turns without having ANY effect. It feels "smooth" and not "bumpy" when it does that. It's so aggravating, I'm looking for a different mouse.

**Q: Can the rgb light be turned off?**
A: You may hit the RGB button on the bottom of the mouse to turn off RGB.            Jason      Support Team      J-Tech Digital, Inc
