I bought the tf-100 kit in September of 2021, a little less than 2 years ago. my pool was replastered so I didn't do any testing for about 6 months. I went to do a test today and my magnetic speed stir only works if I hold the button down, and the light just kinda flickers. Im also super careful with my test kit. Never dropped it and i keep it in my closet so it doesnt get extream temperatures. also my R-0870 powder has turned grey. Anyone else have similar issues and will someone will TFP rectify my issue with the speedstir?
edit: It was suggested to take the batteries out overnight and try again the next day. I did that and the speed stir works. my reagent also seems to still be good. I wanted to update the post in case someone reads this in the future
