T238 NANO Ultra Compact R&G Dual Round Tracer Unit
(Color: Red)

"love it looks really good on any type of pistol i have not tried it on any other guns only on pistols

"The form factor is great and really lightweight. It'll fit in the 4 piece Bulgarian DTK muzzle device, so if you need a solution for 24mm threads and still use a tracer unit that's not 14mm and not the Acetech AK one; you can build this with a Bulg muzzle (aka Krinkov muzzle flash hider). You may need to add a layer of masking tape to shim it good.

Shake awake feature is great. It has a small battery capacity so charging it is fast.

Green BBs are excellent. I did not test with reds.

For some reason charging is picky with what brick you use with. I can't seem to charge it with my power bank. I used an old ZTE charger that only has a 1.5 amp output and it seems like that. It worked with my newer Oneplus Charger (superVOOC). It didn't work with my Google Pixel 5a charger. It also didn't like my car charger wtf.

I personally didn't like the face was clear. I don't like the report it gives when a BB is shot through, so I put down some black electrical tape to cover the face. It helps secure the little white port plug when you're not charging.

It's fine, just a few design choices I don't like. Overall, fine for the price point and it's this or the EMG Helios.
