Customer Review

ATTENTION !!! As my person, respectively. our social institution agsa, mainly relates with good experience goods on Amazon - but have here obtained directly from Pearl - I give due IMPORTANT Info about product here a review from (2 computers: NEW expensive faster Medion Win 8, Older but good DELL computer Win XP) = 2 stroke ordered / related:

1. First of all, to PEARL - Customer service: Short meantime just awful and they used to have a disaster. On 1 are no techn. Inquiries and requests for more jew. Product (which was formerly common and pleasant working) phone answered more, the associated DurchwahlNr. -300 Simply dropped. Everything goes only via email and will not be answered incompletely or not with undue delay, questions. Conclusion: the customer is in the dark! With us came an answer to the request until 14 days after we had the product been on the table. Another thing: complaints are no longer assumed to employees, much of Responsible no longer comes off you, the staff has recently forbidden to connect with each other ... a staff member moaned about this zwischenzeitl. unreasonable (US amerkinischen pattern) working conditions and quit ..... The products PEARL were always ok - supply and return shipments also folded always - but the service is insufficient unsustainable AN absolutely unreasonable, Pearl will only sell and Obviously excl. trimmed to PROFIT -without regard for losses in other destructive price war. Sorry!

2. TECHNOLOGY: Since we no timely techn. Received information, we ordered at random and found laboriously all out for yourself:

a) power consumption with infected PSU: If the computer is turned on (the stroke off) it is still consuming power (regardless of above one of the hubs 4 is switched on / off). Only when the computer is turned off and the AC adapter draws no power.

b) ATTENTION: This hub give it in different versions: one 4x Hub 1x net and 4x HUB + 1xHub / front for charging current 900mA 1x network (we have the first version). Differences arise in the load allocation of 4 hubs that are at 2tern problematic if still Aufladehub power is obtained because the whole acc. Power Supply is limited 20,000 mA and the allocation (unlike 1erstern) per port absolutely at 900mA (USB 2.0 limited 500mA)) - this thing is nowhere described and must be tested with difficulty / remeasured !!
. IMPORTANT Our version, the information regarding the load distribution inconsistent (. Angebl 900mA per stroke at USB 3.0 limits): We run the test two hard drives (one -1TB version- it pulls at 1-plug operation 1.4A current) + 2. USB FP USB 2.0 + 2 sticks (one USB 3.0). When 1.4A FP likely at a limit per stroke at 900mA things do not go. Nevertheless, it does it-even during operation of the stroke without power supply, so it is clear (as long as the load distribution is correct and with infected PSU 2A must not be exceeded controls the individual stroke more than the specified 900mA!

c) It is recommended anyway to stroke without operating infected PSU (if not fully in continuous operation 3x covered up), because it is too much problems and trouble with the computer (Medion computer) even (resp. USB 3.0 Card Dell can cause computer) (there is obviously no internal protection against overload protection and lead to nasty surprises !!). The power supply should be manually inserted to when really more than 2 hubs are occupied and power draw (in our closed operation without power supply with FP 2 and a USB Stick 2.O - but not 3.0 md - until it became necessary plug in the power supply and to ensure operation with the assignment of 3 + 4 stroke, certain awkward but only so it'll work, as described below!)
If the inserted power supply unit (all 4 hubs not in operation), there is a huge problem with two computers at startup. The new Medion computer no longer starts by and goes into a purchase and Auschalt- infinite loop, responding to no off button more so that here the plug was to pull (to here was the 2nd Expansion Board whose hubs in Device Manager no longer recover). Although the Dell computer with old XP started up, but again, the additional USB 3.0 PCI card has been automatically disconnected from the operating mode, no longer recover the additional USB 3.0 in the Device Manager and had to be refurbished each !!). Not forget to pull operation without power supplies then do so, but please plug, otherwise: hence - An absolute disaster, especially since the phenomenon is described nowhere and you think everything is broken - what haber exists only on the operating mode of the hub with inserted power supply The above when switching theater !!
