Easy installation on Mac OS (be careful with one last slightly strange step where you need to turn off the light of the P editor on the device for the computer to recognize it).
Compact in size, with super easy automatic use and compatible labels.
I'm not dealing with Dymo anymore, now that I've discovered this little machine.

I use it for professional purposes, printing hundreds of labels per week, and so far I can say that it is an amazing product. Much easier, faster, and more cost-effective solution than other handheld printers I have had in the past (electronic and mechanical).

Relatively good, it just produces a strange red outline even in black... however, quite fast and economical.

As long as you find third-party labels, this printer is quite cheap to use for labels. It's a shame that ELTA switched to A6 labels, so 70% of the usage that I intended for it no longer exists.

Very good, prints very quickly without any problems and with the help of the very good software, p-touch editor. The label rolls are a bit expensive but available in various sizes, and the advantage is the red and black printing

If you want to stay within this price range and you are also interested in the "red" print, I believe it is the ultimate/unique one. If, on the other hand, you don't care about the "red" print, you can buy the QL-700 which is about 10-15€ cheaper, and theoretically... the same. At the time I am writing this (May 2019), the QL-800 costs 85€, and the QL-700 costs about 70€.

The use for which I bought it is labels on shipping packages. It is very fast and immediate. Assisting in all this, the software (which is not included) has a lot of customization for the labels. I haven't learned yet how to do (if it's possible) multiple label printing, after you have passed them all.

But the biggest advantage is that the paper (at least the genuine one) is suitable for shipments and rough handling, since the plain adhesive labels (printed with a Laser Printer) that I used until now... would fade until they reached their destination (e.g. Australia).
