Device has been easy to use, and simple for a new user. Autofocus works nicely which is important to us; we need consistent results because different people run cell counting as a first step of single cell analysis. Algorithm seems to work accurately as it differentiates between actual cells and cell debris or other particles. Counting with the 8-chamber slide is quite consistent, you just have to pay attention to even pipetting. Measuring with the 8-chamber slide is super easy and quick compared to Luna-stem that we used to use. Getting 8 counts and also saving all the files with two keystrokes frees you to do something else while the counter is running.
