The Casio FC-01A was previously featured on this subreddit.

While browsing online store, I found calculators that looked very similar to the FC-01A.

• Passnaming CP-01A/CP-01A Pro
• Newyes AB0609
• Hypertal CPA

Eventually, will the only calculators permitted for exams such as the CPA be those with these kinds of functional limitations?
Or is this restriction limited to China?

I ordered the fx-JP900CWS and it arrived the next day.

It seems they have plenty of stock.

The instruction manual is already available online, so I won't go into too much detail, but the shape appears to be the same as the 1st edition of CW.

The ROM version of the fx-JP900CWS is FY-531.

It's the same price as the official Casio store on all online retailers, and currently more expensive than the older model.

The Catiga SS-991EX has a good reputation as a clone of the FX-991EX, but I found the Rudnia IP-991EX, which looks similar, on Amazon US, so I bought it.

The accuracy is the same as the SS-991EX, so there are no problems.

However, [ENG] key does not have i label.

Of course, you can still input the complex number even though the label i isn't written, but this makes it a calculator I can't recommend.

I previously posted the following in the comments section, but it's not visible to users who aren't logged in, so I'm adding the content of the comments below.

As has been frequently discussed on this subreddit, the fx-991EX is no longer in production, and obtaining a genuine new unit has become extremely difficult.

If anyone is considering buying a counterfeit fx-991EX, buying a quality-guaranteed fx-991EX clone is better.

Fortunately, we have several such clone candidates, but I purchased this to further increase our selection of clones.

(I don't own an fx-991EX, but I already own several Classwiz EX units in other region models.)
