So far this is way better than the RovyVon A8 and less than half the price! First of all it charges via USB-C not the old outdated micro USB that rovyvon still uses. The button is easier to push and 'clikier' and I like the "memory mode" better too because with a double click it simply goes to the last brightness you had it on. The memory mode with the RovyVon requires you to leave it on the mode you want it remember for 3 minutes. If you're about to buy a RovyVon mini flashlight. Save some money and buy this one!
