Virtually all duplicate games now use bidding boxes. There are a number of reasons for their use, but the two most important ones are to reduce the overall level of noise in the room and limit the chances of the next table hearing the auction before they play hands.
The boxes are really very easy to use and once you get used to them, it will seem awkward to play without them. It is much easier to visualize the entire auction and saves the time needed to review the auction

If you make a mechanical error with the bidding box (pull out a different bid card than you intended), you are permitted to correct that error up until your partner makes their next bid. If your left hand opponent has bid before you discover the error, you should call the director before correcting your bid. Note that a mechanical error is usually limited to pulling the wrong card from either the front slot (a pass versus a double) OR the rear slot (one bid versus a different bid).
