Purchased through Stalliontek- warranty period is 90 days, which I should have researched, but figured that a desktop would be good for at least a year. Worked for about 100 days and quit in mid- use. Purchase the extended warranty or be prepared for a potentially very short run with this device- disappointed, but lesson fully learned.Amazon is not the credible and worry free marketplace that it used to be since they allowed the massive influx of third party sellers into the space- my confidence and trust, as well as my expectations, continue to drop.
