If you use verified machines then it's an amazing and cheap service Non verified machines may be bad, offering bad connections and may be unavailable once rebooted, hence the many bad reviews.

The price is very convenient at about 0.16$/h. Nothing to complain about, for me it was essential to train some DL models at a small price. Very recommended.

Luckily I could reconnect before anyone else jumped on, otherwise it would be a total loss - all data gone. As expected customer service is nonexistent - "we'll be with you in just a minute" = infinite hold
