These flashlight look good on paper and when I received them appeared to be nice pocket sized lights although quite expensive for what they really were. In fact, only one was able to be charged and functional while the other simply refuses to maintain a charge. I guess I have to exercise my warranty rights whatever they are I haven't checked yet.

Only had it for a little while but I like it.

It's small, probably the smallest one I own which is good and bad.
It can be kept/ stored anywhere but it's easy to lose (attached a lanyard to it to keep track of the thing). Not having an anti roll design doesn't help things, but this was probably made for keychain carry.

The light output is good, I like the beam pattern (good spread + hotspot) not throwy.

The charging light indicator at the switch is appreciated (wish the A23 had this).

Wouldn't hesitate to purchase again (and I did).

I am a big fan of RovyVon. I have the A5R and A7U so when the new A3x came out, I had to get one. I got the A3x in Gun Metal grey with the 450 LU Nichia LED. The new A3x is 450, 260, 15, 2 LU. The A5R and A7U are 550, 230, 22 LU. I could tell 450 is slightly less bright than the 550 LU Cree. The Nichia has a higher CRI than the Cree and gives a neutral white tint. The NW provides better color rendition than the cool white Cree. Having a low of 2 LU can be useful when the need calls for it. The A3x is aluminum and weighs 19.5 grams. The A5R and A7U are polymer and weigh 11.8 grams so it should not make a very big difference when attached to a keyring in your pocket. I am hoping the aluminum finish will not show wear and tear from coming in contact with my keys in my pocket over time. I like the fact that RovyVon includes the USB cable (12 inches long), lanyard, pocket clip and stainless steel keyring. My other two RovyVons came with a spare USB cover but not the keyring. I feel the spare cover would be more useful than the keyring. Keyrings are easy to find, but a spare USB cover is not.

Runtimes on the specs show a High of 450 LU for 1.5 mins before a step down to 100 LU and then useable light for 80 mins. I have found with my two other RovyVons, the stated runtimes are refreshingly accurate. The red low battery light on the switch came on after 30 mins of my runtime test on High. During that time, the output went from High/450 LU to about 100 LU after 90 seconds as expected. The light did not get hot while on High. It barely got warm. It remained at that brightness for the next 30 mins or so, then slowly got dimmer to approx 25 LU over the next 20 mins. After a total of approx 80 mins, the light was barely 5 LU. Charging the A3X after my runtime test took approx. 70 mins, just as the specs stated. The Memory mode is new. After the A3x is on the same mode for three mins, it will turn on in that mode. The starting mode will not change until you have it on a different mode for another three mins. The strobe mode is also different from previous models. On the A3x, it is activated by three quick presses of the switch, as opposed to cycling through each mode. This is a nice improvement. The switch is new and will turn red when the power is low.

Overall, I am happy with the purchase.
