This label maker is amazing
This label maker is amazing—easy to set up, fast, and perfect for organizing my home. I used it for the first time on my kitchen storage jars, and the labels came out so clean (just like in the photo I took!). The print quality is sharp, and the thermal system means no ink hassles at all. The app is simple to use and offers lots of cute design options. Overall, this little printer has made my organization projects so much more fun and satisfying.

Wow! What a great label maker!
I recently picked up a NIIMBOT Label Maker, and it’s been such a fantastic addition to my organization game! First off, the setup was super simple. I just plugged it in, installed the software, and I was ready to go in no time. What I love most about this label maker is the variety of label sizes and styles it offers. Whether I need small labels for jars or larger ones for boxes, it has me covered. The printing quality is impressive; the text comes out clear and sharp, which is great for readability. Another big plus is how quickly it prints. I can whip up a bunch of labels in just a few minutes, which saves me a lot of time when I’m organizing or labeling items around the house. Plus, the thermal printing means I don’t have to worry about buying ink or toner, which is a huge bonus! The design is sleek and compact, so it doesn’t take up much space on my desk, and it’s lightweight enough that I can easily move it around if needed. Overall, if you’re looking for a reliable and efficient label maker, I highly recommend the NIIMBOT one! It’s made my life so much easier!

Easy to use. Lots of graphics.
This is a cute label printer. I bought this to make Christmas labels for gifts. The app is easy to download. It's simple to load the labels. So easy to use. It has a ton of free graphics for the labels. There are additional extras that you can purchase. My grandson has loved printing pictures of himself to label his toys with. The graphics are decent for this price! It's compact and charges with a usb-c cable that's included.

I could not live without it
I absolutely love my NIMBOT, it’s easy to use and I have never had an issue with the app. One thing I will mention is I thought it was broken. I immediately bought a new one, knowing I wouldn’t be able to live without it. It wasn’t charging and the light wasn’t even lighting up. I learned after some googling that you NEED to use and USB to USB-C cable. I was trying to charge it with USB-C to USB-C and it does not work. Anyways now I have two of them that work great!

Great gadget but beware of the Subscription
This is a great little product. Easy to set up and use. 4 stars because I think that the seller should be a little more upfront about the subscription service they try to sell you. At 1st it looked like I HAD to purchase the subscription to do anything and I went back and checked the listing - nothing about subscription. I almost returned it but did some digging and there are quite a few templates to use for free. I just always like to know if there is a subscription attached to anything before I purchase it. I'll have to play with it some more to see if the subscription is needed but so far it works for what I need which is simple fun labels for home use.

Best labels and the printer has bold dark blacks
Excellent printer. Bold black that does not smear. There's a lot of different labels available for it. I somehow missed how to use the baleens to keep smaller labels centered, but that works with a bit of fiddling. The app also lets you offset yout text. The app is easier to use than a lot I have tried. I got the red with that retro look.

Functional
Very functional. The printing isn’t fancy but perfect for what I’ve needed so far. The companion app is clean and easy to figure out.

Compact, Cute, and Super Useful Label Printer!
I’m really impressed with this label printer! It’s compact, stylish, and easy to carry around plus the retro design looks great on my desk. Setup was quick through the app, and printing labels is smooth and fast. The labels come out clear and professional-looking, perfect for organizing, product packaging, or even personal projects like gift tags. Battery life is reliable, and the Bluetooth connection is stable. Great for small business owners or anyone who loves labeling and organizing. Highly recommended!

Llevo un tiempo usando la Niimbot B21 y la verdad es que me ha sorprendido lo cómoda que es para etiquetar de forma rápida y sin complicaciones. Es compacta, ligera y la conexión con el móvil es casi inmediata, lo que hace que preparar etiquetas sea muy sencillo. 📦 Diseño y materiales La impresora se ve resistente y bien acabada. Es pequeña, fácil de transportar y el mecanismo de cierre es sólido. El tamaño es perfecto para usar en casa, oficina o incluso para llevar en la mochila si la necesitas fuera. 🖨️ Funcionamiento y calidad de impresión La calidad de impresión es muy buena para ser térmica. Las líneas salen nítidas. Los códigos QR y códigos de barras se leen perfectamente. No he tenido atascos ni cortes raros durante la impresión. El emparejamiento por Bluetooth funciona rápido y sin perder conexión. 📱 App y opciones de diseño La aplicación es intuitiva y permite personalizar bastante las etiquetas: bordes, tamaños, iconos, códigos QR, etc. Es perfecta para etiquetar cables, botes, cajas, archivadores o pequeñas herramientas. ❗ Aspectos negativos Lo que menos me ha gustado es que muchas fuentes, iconos y diseños dentro de la app son de pago. Vienen varias opciones gratuitas, pero si quieres una estética más variada o profesional te obliga a pasar por caja, y eso no se mencionaba claramente. También estaría bien que incluyera algún rollo de etiquetas extra, pero esto ya es secundario. 📌 Conclusión Es una impresora muy práctica y recomendable por su calidad, rapidez y facilidad de uso. Para etiquetar en casa u oficina funciona de maravilla. El único inconveniente real es que gran parte de las opciones de personalización avanzadas son de pago dentro de la app. Aun así, si no necesitas diseños muy sofisticados, la versión gratuita es suficiente para el día a día. Si que es verdad que si tuviera que volver a comprarla compraria una para hacer pegatinas mas grandes.
