Good Product, Somewhat Hard to Read Measuring Cup
930433
The product appears to work well, it's hard to really evaluate how well it promotes healthy bacteria without a laboratory. The only criticism I have is that the measuring cup (built into the cap) is a little hard to read. I used to buy Topfin brand (Petsmart store brand) and their cap/cups are much easier to read.

Pro Tip: the Topfin caps fit the API bottles perfectly. I discovered this when I was switching over to API and saved all my caps.

It's also worth acknowledging that precision isn't really needed. This is a living system so close counts. A drop more or less isn't going to destabilize your aquatic ecosystem, just don't pour the entire bottle into a 1gal tank.

Item arrived promptly and as described. The glass is good for measuring acidic liquids, like lemon juice.  I would recommend if you want a smaller measuring cup.

Wonderful product! I was pleased with the quality of this product as well as the markings on the inside and outside of the cups; the metric measurements; ease of reading the measurements; pour spout and the multiple measurements as well (1/2 cup measure marked on 1 cup). The price point is reasonable.

Very heavy glass measuring cup-just like the old days! Easy to read measurements also.

Reads oven temp accurately. Display could be slightly larger for my old eyes.

The measuring cups have a nice weight and all cups stand on their own. I particularly love the measuring spoons as they lay down pretty flat and don't tip over easily. They also have a good heft to them. I docked a star as the biggest cup arrived slightly misshapen and had a tiny dent on the inside it.

Edit - Upgraded my rating to 5 stars.
Even though the largest 1 cup measure was slightly misshapen,  the measurements were spot on. 1 cup of bread flour was pretty close to the published metric grams. I used the scooping flour into cup and leveling it across the top method, I'm aware that cups are not exactly the most accurate way to measure flour since we all scoop and pack our flour into cups differently, however I was able to achieve consistent metric weights using the method above.

The stainless steel used in this set is of a very good quality and the measuring spoons in this set are also accurate. The handles of the spoon are quite thick and there is just no way I'll be able to bend it. I will be keeping these as my go to measures for American Recipes (I'm from Australia so we usually go by metric here and our spoons are also weirdly 20ml instead of 15ml on the tablespoon measures).

Last but not least, Heather from customer service was excellent and reached out to me promptly to find solutions for the largest cup. I appreciate everything she has done for me and I will definitely repurchase a second set in the future.

The cup is great. The lid works great and the shape stays in tact although it is rubber. It is easy to drink through the lid as well.

The only downside is that the inside of the cup is shaped more like a V instead of a U. The very bottom is narrow so it's harder to reach/clean even for my small hands. That is the only reason why it was 4/5 instead of 5/5.

Overall, I like the cup and would recommend it.

I decided to purchase this measuring cup scale because I love to cook and bake. I also figured that the scale would help me with portion control. Firstly, when I was looking at the cup on Amazon, I didn't realize it would be very large, but when it arrived and I opened the box, I was quite surprised. Definitely not a bad thing, the size. So the first thing I did was I opened up the bottom of the scale where the 1*3V lithium battery is and removed the little plastic tag to get the scale turned on. Second thing I did was I pulled out another measuring cup of mine with one cup water. Then, I poured that water into the measuring cup on the scale.

One side note - you can take the measuring cup out of the scale to clean it with water/soap and just use a damp washcloth, sponge, paper towel, etc... to clean the scale, if it gets dirty. Obviously, you can't submerge it in water because it's electronic and it will get ruined.

So with my water in the cup and cup on the scale, I went ahead and read the measurement reading. It gave me the correct reading of 1 cup, so that was pretty neat. There are also other measurement values that you can use on the scale, so if you want to measure out wet or dry ingredients.

The reason for my 3 star rating, is because just with the slightest touch of the handle, the scale seems to go crazy with different numbers, even when the cup is empty. I read through some of the other reviews here and others don't seem to have an issue like mine. Perhaps I'm just not understanding how it fully works, I need to re-read the instructions, or my scale may be a little defective. However, it is something that I can look past and I'm still satisfied with the product.

One other thing I did try out is weighing a small package on just the scale, without the cup. It wasn't very big, about 4oz, which I knew beforehand, but I added some things to it and wanted to know the exact weight. So that was pretty neat too.

I received this product at a discount price in exchange for my true and honest review. All opinions are my own.

Like the product overall - the part that I dislike is that the instructions are in metric - a lot of converting to inches/centermeters so it is very time consuming and sometimes very frustrating

Works fine, gets the job done. Wish it had markings to show 1/2 cup, 3/4 cup, etc. inside of the measuring cup. Seems like it would be easy to implement and would make it a lot more useful!

I like that this set covers EVERY possible measuring spoon that you would ever need.  However, the markings aren't terribly easy to read.  I have an old set of Tupperware measuring spoons that I prefer, but the lettering is coming off from them.  Guess I'll have to try to find a way to remark them...

This product has been working well as far as accurately gauging the temperature but the display is very hard to read. The numbers on the display are very faint and I can only see them by looking at the device from different angles.

I like that teaspoon/ tablespoon measuring is all in one spoon but the markings wore off after 1 cycle in the dishwasher.  I still use it but I have to squint to read the faded printing.

The cups seem to measure a little large. I use them to measure my dog's food and I have had to be more careful about portioning.

These are a little awkward to swipe across the top, while holding the cup, however, I still like them...they do eliminate some of the mess that frequently occurred from spilling flour when using more conventional measuring methods.  I do recommend them, just wish the tab where you push the leveler was a little larger.

The markings that tell you the size of the spoon are too small to read.  I need reading glasses for smaller print, but I do not like to use them every time I make a measurement.  These markings are just too small.  I ordered a competitive product and it is fine.  I can easily read the branding on the reverse side of each spoon, so the small font was a choice of the company and not dictated by the size of the spoon's handle.  Also, the metal ring that keeps them together (which I like to maintain so that I keep the set together) is too small to allow you to use individual spoons.  A little larger diameter and it would have been fine.  If you don't mind loose measuring spoons and you still have good eyesight, the fit and finish of these were quite good..

I got the two cup angled measuring cup from Oxo because I'm always trying to get the right amount of water for our oatmeal when I'm still half asleep and it's a nuisance using a regular measuring cup.  Knowing this was made by Oxo, I assumed everything about it would be "user friendly".

The concept of the angle, and being able to see where the water is, really does work.  And the handle is very comfortable to hold, but, when it comes to wanting to get 2/3 of a cup of water, the numbers are relatively small and thin and not that easy to read.  The major measurements such as 1 cup is larger and thicker but the smaller ones, in red, disappoint.
