Digital Postal Scale

Easy to use and accurate.

USB 30 seems fairly accurate when checking weight of my packages with Post Office scales.

I have been recently selling things on ebay just so my room be more spacious. The scales really help weigh my stuff and its very easy to use. So far I love it!

I am selling on ebay and this works great for weighing shipments. Seems to be dead-on with the post office scale. I use it through the USB of my laptop as my power source. I also like that I can take it anywhere while using batteries as the power. For the price it should come with an AC adapter. Still worth it though.

I rated this scale low before because it wouldn't integrate with Stamps.com as advertised. I contacted the scale's manufacturer and here is the answer I got. It worked for me. "I believe this may be the answer to getting your scales to work for you. Please try the following instructions. You need to switch the USB scales to the other VID/PID combination which is compatible to Stamps.com and maybe Endicia as well (I read in some forums that Endicia and SDC scales have the same VID/PID which is 0x1446/0x6A73). The instructions to switch the PS311 to SDC VID/PID is: 1. Turn on the scale. 2. Press ON/TARE key for about 5 seconds or more. 3. The scale will restart automatically with SDC VID/PID. This will be the default identity every time the scale is turned on. To switch to Elane identity, you need to do steps 1 and 2 again. Sometimes the hot restart can make the USB scale device unidentified in the PC. To fix this, just turn OFF the scale, wait for about 3-5 seconds and turn it on again. The PC should be able to identify the USB scale."
