I purchased the 5 kg/0.1 gm capable unit, as it will allow me to accurately measure all the ingredients in my bread recipes with a single unit, from many cups' worth of flour to fractions of a gram of yeast. I am impressed by the value this item gives for your dollar. I am however disappointed that although the documentation for this model (5 kg limit) tells you how to perform your own calibration, it does not say what size calibration weight to use. All the other models apparently use a calibration weight equal to their limiting specification, but for this model the chart just shows "--" instead of a weight. I hesitate to purchase a 5 kilogram calibration weight unless I can be assured that a weight that heavy/expensive is what is really required. I am aware that the unit has been calibrated before being shipped, but that calibration will not last forever, and proper experimental protocol requires that I periodically recalibrate by a specific procedure before each test sequence. Other than this issue, I am very pleased with my purchase.

I use this for home baking. Before this, I was using a 5kg scale (accurate to 1g) for larger items like flour or sugar, plus a smaller 2kg scale (accurate to 0.1g) for measuring things like yeast or leavening. I got the 10kg version of this scale so I could have a larger weighing surface and capacity, plus the accuracy of my smaller scale. So far it works as expected, and I'm quite happy with it.

I don't have a set of test weights so I can't speak to strict accuracy, but trying out a random assortment of objects on my old smaller scale vs this new one resulted in weights that were consistent, with the new scale registering each object about 0.2g more than my old one, so that works for my purposes. I don't have any scales that are accurate to more than 5kg so I also can't speak to accuracy in that range.

It's nice to have this much capacity. I can make a full batch of cookie dough and continually tare the workbowl before measuring the next ingredients, without worrying about overloading it. Making a big batch of tea, or brine for poultry is easy now that I can measure multiple quarts and liters of water directly into the stockpot.

I'm using only battery power (it comes with an AC adapter but I prefer the portability and open counter space) and the cheap Amazon 9-volts are lasting for longer than I was expecting. I use the scale almost every day, for maybe 15 minutes a day on average, and I go through a new battery every 45-60 days or so. The battery indicator on the main LCD display shows the status on a scale of 3 bars, so you have a rough idea of where things stand.

The feet are easy to adjust, so much so that picking up the scale and moving it around can move them out of whatever position they were in, so I find myself adjusting one or two each time I move it around on the counter. It would be nice if there were rubber washers or something to make them stay in place a little more, but it's not a dealbreaker. The bubble-level display on the back makes it easy to align the scale plumb to the countertop.

My only other complaint is the downward facing edges of the metal tray are somewhat sharp and not rounded. Since I use the scale for food items, sometimes flour or whatever gets on the surface of the scale underneath the tray, and wiping this area with a towel entails getting my fingers near the tray edges, which can easily cause cuts. If you are using the scale in a similar (messy) capacity, be mindful of this when cleaning it.

These are great, I would give 4.5 stars because the internal battery cable on one has failed. I purchased 3 portable projector hard cases to protect them during car and flight travel. I need to know tenths of grams for my work and these do the trick.

I like the scale very much.

The instruction manual is nearly useless. Particularly regarding the Calibration Procedure.

Even the videos that they point you to for the calibration are not really helpful. The one that is actually present at the link shown in the instructions is very brief, and short of detailed information about what to do if your calibration weights do not include a 2kG single weight or two 1kG weights. For example, is it possible to change the calibration weight setting in the scale to a different value? I don't know because this is not mentioned anywhere.

The second video link is not functional so what ever is not discussed in the paper instructions or the first video is not covered at all.

With good clear instructions, I would have given this item all 5 stars.

I purchased this for the unusual purpose of weighing the carbon ceramic brake rotors for my Corvette (the key wear indicator). I also bought a set of weights to calibrate it. Something went wonkie and the scale ended up reading 10x (e.g., a 500g weight read as 5000g). I got a replacement at no charge. What I also learned, and I believe this is more Amazons fault than the scale manufacturer/seller, is the scale requires a 5kg calibration weight, while the set sold along side the scale on Amazon is only 1 kg total! Rather than trying to round up more calibration weights, I just let it go assuming the scale is accurate enough for my needs. The weight set purchased, thus, was a waste of money (but can be used as paper weights?).

Outside of that gripe and issue, the scale seems to be well design, high quality, and is easy to use.
