What is Reddit's opinion of PH Meter, Digital PH Meter 0.01 PH High Accuracy Water Quality Tester with 0-14 PH Measurement Range for Household Drinking, Pool and Aquarium Water PH Tester Design with ATC?

From 3.5 billion Reddit comments

I got an electronic one for 11.99 bucks! https://www.amazon.com/gp/product/B08LCVBWHG/ref=ppx_yo_dt_b_asin_title_o08_s00?ie=UTF8&psc=1

EDIT: ^^^ this one does not bring buffers for the water, but you don't actually need them. It does bring buffers but it is to calibrate the PH meter (only after a lot of use)

i've heard this one is good as it brings natural buffers to raise or lower the ph without harming the plant:
