Conclusion: (for translation)
The TD03 is a nice addition to the tactical range with a rotary switch and rear clicky, both feel really nice to switch through the modes. This also uses the new SFT40 in 5000K which looks far nicer than the 5700K and 6500K versions. I like the size and feel in hand with plenty of grip from the knurling and matte anodizing. The downside is that it uses a step down timer set at just 20 sec. I'd like to see this removed and use a thermal limit at 50°C. Personally, I'd prefer a lockout position on the rotary switch and perhaps move the tactical mode into the middle position for quick access to turbo.
Pros:
• Build Quality
• Design
• Good Switches
• USB C
• SFT40 5000K
• Beam Profile
Cons:
• Unregulated Driver
• Specs Not Reached
• UI Needs Tweaking
• Mechanical Lockout Only
• Change Rotary Group Positions
