Product Details

Bright Backlit DisplayThis digital scale has a fancy red, backlit display to help ya see your weight readings, even in dim lighting.

Easy CalibrationThis jewelry scale comes factory calibrated and ready to use. Just in case ya need to calibrate it, the JS300 V comes with easy to follow calibration instructions. You'll just need to pick up a 100 gram calibration weight to get the job done.

Does This Thing Count?You bet it does! All ya need to do is weigh a sample amount of pieces, so the scale can know how much each piece weighs, then start counting. You'll be finished in no time.

It Has WeighMeter™ Technology!If ya put too much weight, (more than the capacity of the scale) on any scale it can cause permanent damage. Unfortunately, most scales warn ya of an overload after it's too late. Luckily this digital scale comes with WeighMeter Technolgy to tell ya when you're coming close to the maximum capacity. This will save ya from overloading your scale and damaging it beyond repair.

The Protective Cover Does Double Duty!This tiny scale's hard protective cover is great for keeping your scale safe when ya aren't using it...and it doubles as a nice expansion tray, increasing the area ya have to weigh your stuff on. Since it has edges, you can weigh all kinds of things that would normally fall right off the platform.

Tare FeatureThe tare button on the front of this digital scale can be pressed to "zero out" the weight on the scale. You can then add more weight, and the display will only show the weight of the items you're adding. This sure is useful when ya want to use the cover as an expansion tray to weigh your things, or if ya want to get separate weights of multiple items.

Kill Those Vibrations With VibraKill®Did ya know that vibrations can cause a scale's reading to bounce around from one weight to another? Included with this mini scale is a VibraKill® Pad to keep vibrations, (caused by everyday items like, your fridge, nearby music, your washing machine, etc...) from messing up your weighing.

Man, This Thing Is Tiny!You won't have to worry about this scale taking up space. It's just under five inches long, and less than an inch thick! You can take this scale pretty much anywhere ya want...stick it in a pack, purse, or in your shirt pocket.

It Remembers The Last Unit Ya UsedIf your application needs weights in the same unit of measurement, (like ounces for instance), it can be a real pain if your scale always turns on ready to weigh in grams. It's a good thing the JScale JS-300 turns on displaying the unit of measurement you were using when ya turned it off.

Auto-Off FeatureIf ya have ever had the batteries in something run out because you forgot to turn it off, you'll realize what a blessing this feature is. The JS 300v will automatically turn off after a few moments of inactivity, saving battery power and money.

20 YEAR MANUFACTURER'S WARRANTY!If ya have a problem with this scale within the first twenty years ya own it, just send it in to the Jennings warranty center right here in the USA. They'll fix or replace your scale, and have it on it's way back to ya within two working days.

Great scale - really no faults so far. The customer service from OWKS was fantastic: fast shipping, free upgrade to this model because my original model was not in stock.

I put 3 starts because I don't really know if it's weighing accurately. It didn't come with calibration weight. I could have just paid a few extra dollars to add one to the order. Now I have to wait a few weeks to get paid. Because now I have to pay for the shipping a second time just for the calibration weight. It's partly my mistake because I should have checked, and added it to the order at the time so that I would only have to pay for the shipping that once.

For decades, centuries, even millennia, wretched merchants stood overlooked by the imposing white cliffs of Dover, basking in their awesome might. They spent countless mornings lost in the banks of fog which set in without fail before the sun rose, not to be banished until the harsh rays of midday began to penetrate, and, finally, the merchant could see. But what he could never -truly- see was how AMAZINGLY HIGH-QUALITY and FANTASTIC this amazing device really is! And if you call now we'll include not just ONE, but TWO ounces of the very finest kush California has to offer! It's the perfect thing to weigh out on your brand new Jennings JScale JS-300V Digital Pocket Scale. Please call now, operators are standing by!

Great scale! Greater company!!! They shipped same day, but my Private Mail Drop - UPS Store where I rent a private mail box lost the package and for ten days I waited... turns out a clerk failed to place a pick-up notice in my box... However, when I called WillKnottScales to report that I had not received the scale, a nice young lady, customer service rep, offered to mail out another brand new scale, no questions asked. Now that is CUSTOMER SERVICE!!! I Love WillKnottScales!!!

I recently ordered the Jennings JS300V scales and love them! What a great bargain...they are exactly what I needed! They are useful at home and are small enough to take with you. The removable cover and 8 weighing modes make these scales invaluable. I especially love the counting mode...which allows you to count items right on the scale. You can't get better quality for the price and what great customer service. There's no worries ordering online from Old Will's website! They make certain you are satisfied with the product! I will never hesitate to purchase products from Old Will's for my future needs. Thanks so much for being there!

I was directed to this site when I was trying to find a scale made in the US and purchased this scale under that assumption. I could have purchased a comparable scale made in China for much less. The only place it says where it is actually made (China) is on the outer box. That said, the scale works well. If possible, I would opt out of the HI & BYE greetings when it's turned on and off.

i didn't know which of the 50+ scales available- i called "Old Will's". explained my needs and salesman said the best for me was the JS-300V. my faith in the honesty of mankind was reaffirmed that day - he could have sold me something less quality, much more expensive etc., but the product was just right and arrived much sooner than expected. tks. george
