Sono used on satellites 250w (celestial) for 6 months

the +: - the price!
- Reliable so far
- Own production

the -: - lack of XLR thru line for "string" multiple amps

Do not look for the "big sound" with this type of amp but a good companion
for mid-range speakers (yamaha, peavey ...).
At that price, you will have no surprises
