Due to this thread https://waterpixels.net/forums/topic/2349-aoi-uis-p1-strobe/#comment-20074

I finally bought a pair of these strobes and i would like to write here my firsts impressions, before go into the water, what will be next week.

Before anything here you can see the size of the strobe in compare with other well known strobes, from top to bottom, a Sea&Sea D1, a Sea&Sea YS120, a Retra Pro X s, a Subtronic 160 pro Alpha, and the AOI.

The first impression is that is a heavy and well made strobe, I do like the batteries, I would prefer the 18650 instead of the 21700 but this 21700 is not hard to find either in amazon, aliexpress or any good electronics store. I do really like the screen showing how many shoots you can take with the selected power. I do like the location of the optical connector next to the 1" ball and the type of it, with no threads. I DON't like to press two buttons at the same time to switch it on, I don't like the size of the selector dial, it's to small and in fact there is already in the box an extension knob, which will have to be glued to the dial in order not to lose it.

It comes with a diffuser which I had to use in the water first, to decide if I like its fitting or not and there is also in the box a neopren bag to transport it which instead of it I would prefer a neopren protection cover for the water, anyway its not difficult to make it myself or customize this bag to convert it in a cover.

Next week I write here my first impression once in the water. I will also test them properly in my next trip to Similan island, the plan is 40 dives in the trip, so i think is a good test.
