My latest toy is a weighing scale by Avery. It isn't until you have spent a few years with a rubbish scale, like the DYMO S100, that you appreciate how good a decent scale is. Lets look at the differences:
The Dymo S100: Weighs up to 100Kg. Has a "bumper" round the outside which is only a couple of mm shy of the weighing platform, meaning that if the bag or box sags over the edge slightly, then you get a false reading. The Dymo is very aggressive at turning it's self off, even if you are not using the battery - every time you turn your back it switches off. You CAN get it to stay on... but you have to remember the special button sequence when you switch it on. The display is held in place by magnets which are far too weak for the job, It has a USB power option but that means that it has to be plugged into a mains USB adapter - if you use a power bank, the scale uses such little power that a USB power bank will switch off. The switches are useless - there has been a "knack" to how to press the "on" button since it was new and I think that it is the eventual failure of the power switch that caused it's final demise. The display is on a curly lead that is so fat and curly that it won't fit into the slot that is meant to house it (and the magnets are not strong enough to hold it there) but the lead is not long enough to make it easy to read when weighing a large box. Every time I used it, I expressed my hatred for the useless thing. Especially when I had to weigh large boxes that required a platform (that you had to zero out) in order to be able to see the display whilst not fouling the bumpers. £150 that I regretted spending. I did review the scale on the Dymo web site but they simply deleted it.
The Avery ZM110 by contrast, is a great bit of kit, weighing up to 150Kg. It has a large (40x50cm) weighing platform that is 15cm off the deck, so it is never going to give a false reading. The the weighing surface is stainless steel, which is not important for me, but essential if you are handing food. It has a mains adapter plus a built in 170 hour rechargeable battery, enough to keep it running for a week. The display is huge, backlit and super easy to read. The display is easily visible over may largest boxes but even if it wasn't, I could twist the display to be viewed from the side or the rear. The only catch is: Don't buy it from Avery! They wanted £454 + VAT. I threw my hands up in horror and a few hours later they revised that down to £363 but I had already googled and found it at outweigh.co.uk for £225 + VAT with free delivery in under 24 hours. It was a bit of a faf feeding cables through the stand tube but now it is sorted, it is a pleasure to use.
Avery rocks, Dymo sucks.

Good little scale, nice big display, easy to use & very good value for the money.
