As part of my job I test and use many different models and brands and for my personal use with our MAC computers we use the DYMO label printers. We have units that print labels, plastic labels and postage and find this product as one of the all time great time savers and a great value.

I have used several Dymo printers in the past 10 years and generally they work well. This model does have a few issues. When printing more than one postage label it will misprint or skip a label or not print a stamp about every 10th time. As a result, I am wasting several stamp costs each month. This occurs more if printing more than 4 stamp labels, so I keep it to 3 or fewer each time I print. Even then, it might skip or misprint. The monopoly Dymo has on the postage labels is annoying. They claim to not support any other labels, yet price these labels significantly higher in cost than other labels where they have competition. 

I've had my 450 Twin Turbo for almost two years now, and it's one of the best things I ever bought for my home office. The option for two label feeds is a must, so that one feed is always reserved for stamps, and the other feed is for all of the various types of labels I use. The printer is fast, quiet, small, looks good, and best of all doesn't need any toner refills. The software for labels and stamps is quite comprehensive, yet very easy to use. I recommend this label printer for anyone who wants to keep their life organized and efficient. It's handy to have such a customizable label printer, and I haven't had to stand in line at the post office in two years. The variety of labels that the 450 Twin Turbo can handle and that Dymo offers is impressive - you'll find no shortage of things to label after you get this printer.

We purchased this labelwriter to print both postage and UPC labels. For our business we need to use 1" x 1" labels for UPC A, which the software will not support. It will not allow you to shrink the UPC to fit within the 1" area. What a waste to think how much money your company may be losing to companies who have to send out to a third party to print the exact same thing they could be printing in house.

Saves so much time with certified return receipt mail. I also like having the address book, that saves time. Have had no problems with it since I have had it at lease 2-3 years. Also, the clear address labels come in handy for legal documents, for labeling attachments, exhibits etc. I also Label Binders. I would definately RECOMMEND. Money SAVER 4 Sure!!!

I have using Turbo 450. Was working with Catalina. Purchased Twin Turbo and now I'm in trouble. I tried to install the Twin Turbo on the same Mac as the 450, but the printer wouldn't show up in the printer list. I tried to update software, but Apple would not permit it because it couldn't be checked for "malicious content." I thought I might need to uninstall the old software and use the new software, but the was really dumb and a HUGE MISTAKE. Now I have no software that works. DYMO need to update the software for Catalina 64-bit. Don't purchase DYMO until they do.

The Dymo label writer has saved me lots of time addressing packages and standing in line at the post office. The labels look professional and even have my company logo on them. The only cons are that you can't turn it off without unplugging it, and that the machine gobbles up labels once in awhile.

If I could give it zero stars I would. Thanks to a recent software update this once great product is now a worthless piece of ... The update not only erased my many important files, it no longer even has the TEMPLATES i was using so I can't reconstruct them. Thanks for ruining something I really needed DYMO!!! :(

Like the reviewer below, I also have problems with the printer 'sleeping' and never waking up... that is, until I turn the unit over, unplug BOTH the power AND the USB, wait for 60 seconds, then plug everything back in. Only then with the blue PRINT button appear in the application. On top of that, there are still no drivers available for Big Sur (macOS 11.x), and it's been out of beta for 6 months.

I have purchased and used over 100 Dymo LabelWriters in my multistate retail stores and warehouses, and loved them. Now with the RFID chip on the Dymo rolls, making it impossible to purchase less expensive labels, I am phasing out the Dymo LabelWriter in all locations. It makes me sad, Dymo has been my go to printer for over 10 years
