I've been using this scale for 6 years now, and the calibration 'strayed' off once. It was last year by 0.02gm.
I took a minute to re-calibrate with my calibration weight and it's back to dead on every time since then.
One irritating thing is the auto-shutoff is getting even shorter. I guess the capacitor is getting old or something.
The scale now shuts off after 30 seconds of no weight change. Pretty much means I have to turn it back on
for each item I weigh. It doesn't take more than 3-4 seconds to come back up, but it's IRRITATING...
July 2009 Review:
This scale has stayed calibrated for 6 months. I have a 50g and a 100g calibration weight. I calibrated the scale the first time I used it, and it has stayed dead on every time I reweigh the calibration weights.
I deducted one star though for a frustrating 'feature': the ridiculously aggressive auto shut-off engages after being idle for 45 seconds! Just about every time I reach over to put the next item on the scale, I have to turn it back on first. VERY irritating. It should be at LEAST 3 mins, and I think 5mins would be reasonable. Exactly how much 'juice' does the scale use sitting idle anyway? Can't be MUCH!?
My previous scale (which gave up the ghost and in retrospect I'm glad it did) was much more costly, much more finicky and had an annoying shape to the weighing platform. This is smooth, sleek and the controls are easy.
Another nice feature is that the instructions are on the inner lid, and the printed ones that came with it, are very short, simple and don't presume extreme stupidity on the part of the consumer--"please don't use while standing on train tracks as vibrations will interfere with accuracy and collisions may be fatal"--nope that warning was NOT present thankfully.
Just make sure you have a calibration weight--100 grams. This was also easily obtained from Amazon (and with prime shipping). My previous scale had a 'zero' button, not a real calibration, so this is a nice step up.
Great quality item for a reasonable price and highly recommended!
I don't have a great way of determining whether my new scale or my new calibration masses is precise, but I found this scale read within about 20mg of the specified weight of each calibrator (or group thereof) from 100mg down to 20mg. I found that it will not sense my 10mg mass weighed alone, but it does settle accurately on the 20mg mass given enough time. As has been noted elsewhere, the sleep timer is short--just barely longer than the settling time for weights in the 10-20mg territory--so I have got into the habit of either leaving a first sample on the scale until ready with the next sample OR lightly brushing the scale with my fingertip periodically to keep it "alive" between weighing operations.
LATER: Drastically editing and changing this review on the basis of having actually tried to use this scale to weigh things. Here are the issues:
* Sleep timer fires sometimes even when you're in the process of weighing stuff, so it has an irritating tendency to go to sleep right in the middle of weighing operations. This necessitates a re-tare if you were doing anything more complicated than weighing reference masses.
* If the weight on the platter decreases, the scale bounces down to zero and re-calculates the current weight again. Not usually a problem but definitely bothersome.
* Settling time is fairly long compared to sleep timer...often I find that the weight reading is still swimming around when the scale goes to sleep.
* It is not sensitive to changes in weight of under 10mg, maybe under 20mg.
* I would say this is actually a scale of about 30mg precision with a readout of 10mg precision.Read more ›
