The Good
It's very inexpensive and sufficiently separates CD3e+ cells for gross enumeration.
The Bad
It does not completely separate CD3e+ cells from CD3e- cells.
The Bottom Line
If you are simply enumerating cell populations based on surface marker expression (e.g., T cells, B cells, macrophages, etc.), this antibody is great. If you need to be very confident that you are only looking at T cells, you should probably select a different antibody.
