This is revision 4 and counting. You slammed me for using harsh words to criticize the first few revisions of this product, but I believe my criticisms are still being held up as valid. The language may have been a bit much but the main points were pretty valid. If you were one of the many readers of XS Liquid Cooling who spent your hard earned $129 to listen to cavitation for weeks on end, you might consider some of the unhappy campers. Not everyone has a $2000 water cooling budget with which to experiment on poor revisions of this reservoir time and time again.
Wouldn't fill and bleeding problems be solved with a simple T line before the first pump in the series, and keeping the first pump at low speed? Its not like the WC community hasn't already been doing that for years -- I see this product more as an excellent way to get a pair of D5s into a pair of 5.25" bays with a rez built it. The 452 will help bleeding and potentially filling the system, not as the sole fill and bleed point.
