Hi, thanks for the attention on the Nitecore TIP2017. And your concerns are certainly valued.
The utility clip of TIP 2017 is a very useful included accessory. It offers more carry options and allows you to cover the buttons and prevent accidental activation when it is not used.
It is also removable and flexible. If you don't need it, you can take it off and put it away. If you want it to cover the other side of the light instead of the button, you can adjust it.
Regarding the 30s auto off, it is the functionality in the Daily mode, which is designed for applications that require temporary lighting such as finding your key in the darkness etc. It is normally adequate.
We understand that there's possibility you might stumble for more than 30s to find a key, therefore we have added a TEMPORARY constant lighting function in the Daily mode as well. Once the light goes off automatically after 30s, you can immediately press the On/Off switch to have constant lighting (just for this one time) to get your job done.
If you want to have constant illumination not just for one time, just simply hold both the power switch and mode switch until the LED flashed twice to enter the constant-on mode.
We have considered the possible scenarios so as to make the product better. It is very easy to use.
Thank you for your valuable opinion.
