content: I'm in need of some customer service with regard to the EEVBlog 121GW multimeter. I purchased the meter a few months ago through Amazon in the US. Almost everything is fine, but the 1mS PEAK button has to be pushedextremelyhard before it will do anything. (I've not had the meter apart to see if I could fix it or determine why this might be a problem.)Several weeks ago, I sent a message to the warranty claim e-mail address given in the user's manual, but have not heard anything back. I understand that these are unusual times, and perhaps that is why.I'm not sure what to do at this point. Any help or pointers would be appreciated. Likewise, if this post is misplaced, a gentle correction would certainly be appreciated.

content: Sending an e-mail to the address in the March 2020 manual is exactly what I tried. I do not have any reason to believe it would not have gone through...

Probably some contaminant or object there. An isopropyl should work.I only recall one other report of something like that, so pretty rare.

content: I will try cleaning the underlying pad to see if it helps! (I have to admit I find the possible need to do that a little disappointing, but if it works, that's good enough for me.)

content: In case anyone happens to be interested, the problem turned out to be a small piece of metal sitting across the underlying contact pads. I'm surprised it never caused "phantom" button presses. With it removed, everything seems to be fine.I suppose it was the excess lead trimmed off from some component or another.
