I agree.
I have had a few myself. From old ISY44i and ISY994i.
With one. The ISY994i was OK until I did a power cycle on it. Then all it did was start to reboot and the supply shut down and the cycle repeated. One nice thing was the ISY994i has a wide power input range, Mine where originally 5V 500ma and 5 volt 1 amp. Now I have 12V one amp.
