Hi,
Assuming that I have a design intention for a mobile phone and I would like to confirm whether it works well as i expect. Is it appropriate to use "valid" or "effective" in this situation?
eg: The design improving is not valid since it has been proved ineffective in our test.
Also, if I want to tweak my sentence as below which words with the underline are correct or more natural
eg: The design improving is not valid since it has been proved ineffective for using?/applying? in the effective?/actual? life.
Thanks for giving me your kindly explaination
