I bought this printer because I hate manually writing addresses on envelopes. I also grew tired of having to remove paper from my ink jet in order to insert envelopes for printing. The Dymo LabelWriter 450 Twin Turbo allows me to print address labels on one side and postage stamps on the other. I use a LabelWriter 400 Turbo for 3-part internet postage shipping labels. I could not be happier with these products!!! I highly recommend them!!!

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!!! :(

What a piece of CRAP! This software is basically unusable. I don't understand what their customers did to the software engineers to motivate them to write such bad software? I've used Dymo products for decades and I've never seen anything so terrible in all my life. I know it might be difficult to hire good programmers these days but any college student could write better software than this pile of CRAP!

The 450 Twin Turbo LabelWiter works great for address labels and postage. A big drawback for me is that this model is NOT included in eBay- compatible labelmakers (as of late March 2013) for their address label-making utility. eBay has been notified of this shortcoming, but they have not responded.

I have used the Twin Turbo for a couple years and love having professional labels complete with bar codes for mailing. I especially like being able to verify addresses to be sure the barcodes are accurate to speed my letters through the Post Office. Postage is easy coupled with the Dymo postage scale.

I've had two of these particular machines, and I bought the second for my wife's business because the first worked so well. They produce high-quality prints, are trivial to load and unload, and are rock-solid from a reliability perspective. Learning to use the latest version of the software wasn't as easy as it should have been, but it wasn't an insurmountable problem either. Disclaimer: I write software and have done so professionally for a long time, which probably gives me an edge in figuring out the current release of Dymo's. Pro tip for Dymo: expose an API (i.e., create an SDK in a popular language) for the printer's firmware that would allow third parties to write applications that can format labels and send them to a Dymo printer. You're in the label business (and in the marginal hardware business), not software: make it easier for the world to print more labels.

This thing is nothing but problems, never works correctly, stops connecting to the computer. I've had to delete the program off and then re-download it to get it to work again. Jams and keeps feeding, will just start printing blanks and not stop...It is not worth it...

I've been using labelwriter printers for just shy of 20 years now. I have owned multiple 450 twin turbos. I agree wholeheartedly that the latest dymo software is absolute garbage compared to what they had 15+ years ago. Bring back the old software.

Label printing is good, but when installing the software, windows 10 only recognizes 1 printer, not 2 as indicated in the documentation. Since I do not use Dymo connect to print labels, I have to go thru printer preferences, adding multiple steps for something that should be as simple as changing printers.

Works well enough... but not overly impressed. Does not print both sides simultaneously which would have been helpful to me. We use it to print barcode labels, and shipping labels. It skips labels a lot, or has blank spots on some labels. Sometimes prints extremely slow at times and extremely fast at others. Very unpredictable. But works well enough...
