Features:
- EFM8BB21F16G MCU pipelined 8-bit C8051 core with 50MHz maximum operating frequency.
- A dedicated high-frequency driver makes the start more smooth. ESC maximum speed is 500k eRPM.
- BLHeli_S firmware is designed for superior performance in multirotors and uses hardware generated motor PWM for smooth throttle response and silent operation.
- Damped light does regenerative braking, causing very fast motor retardation, and inherently also does active freewheeling.
- The code supports regular 1-2ms pulse width PWM input, as well as Oneshot and Multishot. The input signal is automatically detected by the ESC upon power up.
- Supports Dshot150, Dshot300, and Dshot600. Dshot is a digital signal, the anti-interference ability is stronger, and do not need throttle calibration.
- The silicone twisted-pair of the throttle signal cable increase the service life, and effectively reduces the crosstalk caused by signal transmission, and makes flight more stable.

Its alright
Color: Black, Size: 5X-Large
True to size per the size chart. The fabric is soft but it it feels cheap to me. It attracts lint but you can brush it off easily so its not the cheapest material I've dealt with. Also, it is opaque (not see through).
There is no front/ back indicator either which is indicative of a cheap shirt in my opinion. Would be friendly for tag sensitive people (to stay positive).

Fuzzballs get wearing once
Color: Black, Size: X-Large
Very smart to wear, but the quality is terrible so after one wash the collar start fraying and fuzzballs start forming.
Very disappointing.

Amazing quality and well worth it!!!
Color: Black
Great watch! My son saw his friend have and was impressed so I got him one! This one doesn’t have a connection point from the band to the watch so it can’t break there which has been the issues with all his other watches. This is easy to setup and use! It worked so great that I got one for my other son! They both say the size and options are perfect! Highly recommend!

Great classic timepiece
Color: Black/Digital Gray/Silver-Tone, Color: Black/Digital Gray/Silver-Tone
I’ve been using the Timex Men’s Ironman Triathlon Classic 30 (38mm) for a while now, and it’s easily one of the most dependable watches I’ve owned. The design is simple but functional — lightweight, comfortable, and perfect for workouts, outdoor activities, or just daily wear.
The Indiglo backlight is super bright and makes it easy to read in the dark, and the buttons are responsive without feeling flimsy. The stopwatch and countdown timer features are straightforward and accurate, which I really appreciate for timing workouts. I also like that it’s water-resistant, so I never have to worry about it in the rain or while swimming.
The 38mm size is just right — not too bulky, but still sporty and easy to read. The battery life is excellent, and the Timex durability definitely shows; this watch can take a beating and still look good.
If you want something rugged, affordable, and practical, the Ironman Classic 30 is a solid choice. It’s a no-nonsense watch that does exactly what it’s supposed to — and does it well.
