Easy to use. First time I tried it with no problems. Same result at mash temp and room temp. Good value and straight forward.

If you do a internet search you will find there is a ton of information and opinions on the effectiveness of these strips. I have been using them for years and have been been happy with my end product. As stated in other reviewers posts you should adjust the reading up .3 to have a fairly accurate reading. There are other considerations. The strips have a five year shelf life if kept completely bone dry. I vacuum seal my strips between batches. They have a 1-2 year shelf life when exposed to air. The strips should be left in the wort sample for at least 1 minute and up to 10 minutes to get an accurate reading. I usually set a timer for 2 minutes.

I have used these on two different batches. Extremely easy to use and very accurate. The last batch we had a pH meter and they came up with the exact same readings.

The best strip on the market.

Good for getting into water chemistry. If you're brewing once or twice a month like me a pH meter may not be worth the investment. This is a more than suitable option.

Just follow the directions and check the the mash PH for a better brew.

pH meters are a pain to calibrate prep and store. These strips take away additional processes during brewday. Research indicates they read about 0.3 pH points lower than a calibrated meter around mash pH so take this into account.

This is a cheaper way to check your pH than a pH meter and you don't have to worry about keeping them in the storage solution or calibrating them.

I bought these after listening to a podcast with Jamil Z on the brewing network where he discussed their benefit. I've used other ph strips that are next to impossible to read. These strips while more expensive than others are much easier to read.

They work as expected. I'm color blind and need to grab my son or wife to help me interpret the color. They are cheaper than a pH meter and do what they are supposed to do.
