The available aggregate rating is 4.0 out of 5 from 9 ratings. The distribution is sharply split, with 75 percent at five stars and 25 percent at one star, so the average alone does not show why experiences differ. There are no qualitative customer comments to explain those ratings, buyers should weigh the intended expansion use and confirm system compatibility and capacity details.
