What's great about this product:

• One of the best things about the 1648 is its incredible speed. It's capable of opening up to 12,000 No. 10 envelopes in just one hour. It can accept a stack of mail that's up to 5 inches high for processing and will automatically open it. Once the envelopes are open, the 1648 will automatically re-stack them for you so you don't need to waste time straightening them up.
• The envelopes the 1648 opens can be up to 3/8" thick. This is a feature lacking in some of Martin Yale's other opener, such as a the handheld 1624.
• This machine opens envelopes cleanly every time. There's even an knob you can tweak to control how deep into the envelope the device cuts.
• The catch tray can be stored on the back of the machine when you're not using it. This can help you save some space. That said, this machine isn't particularly big to begin with. It has dimensions of 21" x 10" x 11" and it only weighs 18 pounds.
• The 1648 is very safe to use. This is because the blades are hidden deep within the machine. That way, your fingers will be far away from the blades.

And a caveat:

• This machine opens an envelope by literally slicing off a part of it. This means that, if you don't jog your mail before placing it in the machine, you risk getting your documents damaged. So be sure to either tap your mail on a flat surface or place it in a paper jogger before running it through the 1648. That way, your items will be at the bottom of the envelope and they won't get damaged.

Conclusion:

The Martin Yale 1648 Automatic Letter Opener is the ideal choice for workplaces that need a device that can process thousands of pieces of mail per day. It's extremely easy to use and it makes processing a lot of mail a very quick process. You can literally just insert the envelopes into the machine and let it go to work.

It's also safe to use and has adjustable settings so you can get the exact results you want. Just make sure to jog the items before running them so your documents will be in great shape.
