Reliable, simple, and perfect for everyday organizing
I’ve had this Nelko label maker for a couple of years and it’s been one of those small purchases that ends up being used all the time. Pairing it with my phone was straightforward, the app is easy to navigate, and I like having lots of templates/fonts so I can make labels quickly without fussing. Print quality has been consistently clear, and it’s great for pantry bins, storage boxes, file folders, and labeling cords/chargers. It’s also compact, so I can toss it in a drawer and pull it out whenever I need it. Only thing to note: it’s made for quick phone-based labeling, so if you want something that’s more “computer/printer” style, this probably isn’t that. For simple, everyday labeling, it’s been excellent.

Works great!
Great little label maker. Easy to use, lots of options for font size and types, graphics, etc. Very small, can fit in pocket. Labels stick well. No smudge printing. This is the first label maker I bought since the old style so many years ago. Usb rechargeable. Good for small labels only.

Great label maker - super easy to set up
Easier to set up and start printing than a regular printer. Download the app, connect, and make some labels! The app where you edit and create labels is really good. You can even save templates in the app and the files are saved across devices. The print quality is pretty good and it’s fast. Very happy with this label maker.

Great product for a great price!
This Nelko Label Maker Machine works better than I imagined it would, especially for the price. I love the different choices of designs options we get. I use the labels for many things around the house. I thought the best part was that we can connect it through bluetooth and its very user friendly! Print quality was clear. The size is convinient because I can take it with me to use anywhere.

Worth every penny
Its perfect and compact. Prints anything you can fit in the small rectangle and you can even get images online to print on them. My wife and I use them to label everything around the house and she loves it for work. Easy to use with every tool needed being on the app and works very good and is built to last.

App-controlled label maker that’s easy to use and prints clearly
This label maker is compact, lightweight, and very easy to use. It connects to a mobile app, which makes designing and printing labels simple without needing a computer or extra buttons on the device. The app is straightforward, and the labels print clearly with good adhesion on containers, bins, and other surfaces. It works well for home organization, office use, or labeling storage items. The machine itself feels solid and doesn’t take up much space when not in use. A great option if you want a small, app-controlled label maker that gets the job done without hassle.

Well designed little label printer! Review and how to use.
This smart little printer has a dedicated app with an easy to use interface and plenty of free templates to choose from. It charges with USB C which is great as most people have a few of those cables sitting around. The labels are waterproof which is a great plus thanks to the fact it doesn't use ink but instead a heating process to stamp in the labels. It comes with a roll of 180 labels, 14 mm x 40 mm or 0.55 x 1.57 inches, very standard size. Currently on amazon 3 extra rolls (540 labels) from Nelko is $16.99, although for most people 180 will serve plenty. The product is easy to use. Click P21 on the top left of the app and click to connect, you'll hear a little beep. Before your first print you'll have to open it up by sliding the notch at the top (doesn't have to be slid all the way) then put the label on the track, then the button should turn blue. When you close click the button twice and it'll calibrate the label on the track. To print, use a pre-made template (14 mm x 40mm) or create your own, click "EDIT" then the print option comes up, click print again and like magic it heat prints without ink. Hold on the button to The quality of the heat print is very good, deep black and filled in near perfectly in the lettering. At this price point, you are getting an excellent product, and the labels will last longer than simply writing things in with ink, not to mention look much better. I use these for my keys, jars among other things, very nice little machine, highly recommend!

I like it.
Easy to use. The app could have a cleaner interface. It is nice and small. Connects to app immediately. I’ve printed a few labels and nice details. I expect/hope since it’s a thermal printer there should be zero fading.
