Hello,
recently I recieved my Gamsir T1S (Gamesir T1S Wired Wireless Bluetooth GamePad Controller For PC PS3 Android Phone | eBay). I actually bought and returned a Gamesir T1D in the past because I couldn't stomach the latency introduced by bluetooth connection.

Here's what I discovered:
With bluetooth connection Gamsir T1S and T1D both have latency of 1~2 seconds + messes with video feed even with Xiaomi Wifi 2 range extender.
With Gamesir T1S connected to the phone using OTG cable has latency of ~0.25 seconds, and no problem with video feed with or without Xiaomi Wifi 2 range extender.

Bottom line, gamesir T1S is slightly more expensive ~10USD than the Gamesir T1D, and there are a lot of package deals out there being sold with Tello + T1D. Don't do it!

T1D cannot be used for anything else and inferior to T1S even for controlling the Tello drone.

As for T1D, I really like it except the feel of the right trigger and how light it is compared to my phone. I am also starting to use it for PC gaming and it's a whole new experience for me.

Sorry but I disagree
I have T1D connected with Bluetooth and don't see the lag that you described...
I use it regularly with no issue at all

I guess experiences may vary, is there anything special you do with it? Wifi extender, Gamesir firmware , etc.?

Certainly a wired otg controller significantly reduces video delays, but on some devices the gamesir T1d manages to perform much better than other smartphones. it is essential to have a wifi extender for the tello and with the addition of a parabolic reflector I managed to get a good video at that distance and I could go further ....

Nothing special.. with and without Mi WiFi extender I get good result with it..
I always use it .. and I found it very useful (personally don't like to control Tello with smartphone touch screen commands.. I prefer physical sticks)

I see,

have you tried a controller with OTG cable for comparison. Maybe latency is less noticeable and shorter with your setup than mine but OTG should always be at least slightly faster.
