It might be a little bit cheaper than blulab for instance, but it's just as good as an expensive model.

But if you are on a budget and are using a tester to check the PH of say swimming pool water, a cheaper model will work just fine

I found that cheaper models were less accurate and stopped working quite quickly

I went through two slightly cheaper models with exposed sensor bulbs.

Will definitely buy another or a better model

I purchased several cheaper models that quickly failed to hold a accurate reading

(I have tried 3 other cheaper <$20 models)

And as long as you occasionally test and re-calibrate them, you are better off with two cheaper models than the one more expensive one that does the same thing.

I have tried the lesser models of competitors and regret it after purchasing this Apera unit

I chose this meter over the cheaper models since it has easily replaceable AAA batteries and it just seemed a little better quality

I'd keep enough of it in the cap to submerge bulb and replace weekly with 4 ml of fresh 3M KCl.

I have had several other brands including bluelab & H M and like how the Apera pH performs

This meter has a nice cap with an O-ring that does not leak, so I expected it to last a while
