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

Great communication Great communication, was updated step by step the progress of my order. The item itself was really, really cool. Whoever designed and built these earbuds really outdid themselves. I am very knowledgeable in electronics and I was really impressed.

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

Alpha65 Fast Wall Charger War-Damaged Blaze Blue Great charger works awesome, fast charge no overheating and I have used it on numerous things. Really like the mecha design of the charger and the light up eyes make it so cool - good quality with attention to detail all better than I expected. Best Regards from Poland

Excellent product Gravastar is excellent with communication, the product looks, feels and performs on a premium level. My only gripe is the logistics area needs to be improved upon, it took exactly 3 weeks to (finally) get the product to me, when I know orders from overseas can easily be delivered here within 7 working days.
