it wouldn't be able to stand up to heavy

An electric comb binding machine is a
great choice if you like the look of comb binding but want to make the
process a little bit easier. One of the better electric devices
available is the GBC CombBind C110e. It's an entry-level binder that's
great for offices that want to bind a few documents a couple of times
per week. Here's a list of this product's strengths and weaknesses....

Strengths:

• The C110e has a pretty good binding capacity of 300 sheets. This should be a good enough capacity for a lot of potential users.
• This
  product can also punch 15 sheets at once. You can do it simply by
  pressing the button located on the left side of the machine after
  you've inserted your paper into the device. Since there's no handle
  that's located on either side of the device, the chances of developing
  or aggravating a repetitive motion condition (i.e. carpal tunnel
  syndrome) are slim.
• You can use both plastic combs and GBC ZipBind spines with the C110e. It has a storage tray for your supplies.
• Vital
  parts of this machine are made from metal, including the comb opener.
  This is fantastic because a comb opener with plastic parts (especially
  the teeth) would be rendered useless after a period of time.
• The machine has a comb selector guide to make selecting the right supplies for your books a little easier.
• Both
  plastic and oversized covers can be used with this device. There is an
  adjustable edge guide that makes working with oversized covers both
  possible and easy.
• The C110e has a nice, contemporary design
  that should be appealing to a lot of people. It's also pretty
  lightweight so you won't struggle when moving it. (The product weighs
  in at 24 pounds.)
• This is a very affordable product and it comes with a limited one-year warranty you can use if problems arise.

Weaknesses:

• Although the 300-sheet punching capacity is good for an
  entry-level comb binding machine, this does mean that the device isn't
  ideal for organizations that routinely produce longer documents. Not
  only can it not punch a super long document, it wouldn't be able to
  stand up to heavy, frequent use.
• Like some of the other GBC
  comb binding machines, the C110e doesn't do well if you try to punch
  plastic covers with it. If you decide to do so, make sure you don't
  punch more than 2 per lift. Trying to punch anymore will cause
  problems, potentially even damaging the motor.
• This machine
  lacks disengageable dies, so you will mainly be stuck with creating
  documents that are 8.5" x 11". Trying to create books that are larger
  or smaller than that will be tricky and may not be possible at all
  unless you get creative.
• There is also no adjustable depth of punch margin control so you won't be able to dictate where your paper is punched.

While
the C110e lacks a lot of the features most often found in higher-end
devices, it nonetheless is a reasonably priced product that would be
great for offices needing an electric comb binding machine for
occasional use. It's entry-level for sure, but it works well, and it's
a great value, so get one for your office today.
