Fast and reactive Fast and reactive. Can't tell the difference between this and a wired mouse. In fact, adjust sensitivity settings. Love it!

A fan of Gravastar Just got my M1 battle worn mouse and 4K dongle plus the mouse pad and I have to say it did take a while to get it but there is an old saying ( Good thangs come to those who wait ) l realize sometimes we humans can get a little impatient when something amazing and will thought out and beautifully handcrafted comes along and we the people jump on said handcrafted item such as the M1 battle worn gaming mouse . The overall products and pain staking craftsmanship that goes into these gadgets is what makes Gravastar unique. I know I can only speak for myself I haven’t been disappointed with the Bluetooth speaker the ear buds and now this gaming mouse. I guest in a roundabout way I do want to apologize for being a little impatient with getting my gaming mouse. With that said I know I will enjoy the products that I purchase from Gravastar they will serve me for a long time . Again I appreciate what you guys do for us your customers.

The best products ever, with great support! I had the ability to speak with someone on gravastars team about concerns I had and they reached out within 20 minutes I mean fast. It was awesome they were very kind helpful and helped me track my package with ease. Plus I love my speaker it loud awesome and gets lots of compliments and my little delta 35 charger is so cute and charges everything quickly and doesn't make my phone or my gravastar ear buds hot and feel like it's on fire. :) forever a gravastar customer <3

Durability is a HUGE issue! Really not impressed with the earphones I've bought. I purchased the Sirius P5s and the connectivity of these things is embarrassing. I can't go anything over 2 songs without them cutting out and going fuzzy; the volume is also a huge problem, with one earphone always being slightly quieter than the other. For the love of god, just go for another brand of earphones that are more durable than these. It'll save you the frustration, trust me.

Very good products I enjoy the product very much but the problem is with the cases of the Sirius Pro not being stable, like the latch doesn’t work one of two pars, after about a year of using them without issue, the latch just random stopped keeping the earbuds close. Ive ordered all the different speakers and they’re all amazing
