[Set] R504 - Tan [Army Armament] + Eshooter Flare Cube BT Tracer Unit [ESHOOTER]

Nice quality, many functions, works as intended. Using it on my CM.131 AEP. High rof is not an issue, the App is also very convenient for switching colors and modes and chronograph is accurate when compared to a standard one.
I would recommend it.

SUPER nice! For this price, you get flare unit, tracer unit and chrono, all in same baggage! Phone app to see chrono readings and to change some of the settings. Most settings, including flare and tracer mode/color etc you can change with just push of a button, or actually two. Charge port (type C) is in front, so no need to remove unit. Chrono with app is really good and give you fps and rps (or m/s and rpm), what ever you need. I did compare chrono results with my "Shooting Chrony M1 Master", only 0,2% difference there for speed, but I have no way to get accurate reference for RPS, but seems to be in line with how fast my mags go empty. BEST PURHACE EVER! I may buy even another one, it is just that good.

This tracer looks is very good, i like it's customizations, it even has a chronograph inside of it, it really surprised me
Pros
Chronograph built inside of it
An app that can be downloaded(It lets you access chronograph and a lot of customizations)
Can be fastened (such a saver for me, because I lost my flare M tracer in first game)
Has 4 modes: Flame, Tracer&Flame, Tracer, Drag Light
Charger is in front (You won't need to detach it for charging anymore)
Has 2 fastening screws in case you lose one
Cheaper than flare M tracer
Looks cooler than flare M tracer
Cons
I haven't found one yet

If you are thinking between tracers for your pistol, in my opinion, this one is the best option
