Has anyone used these cheap HK ESCs?

For six bucks apiece, these seem too good to be true. Does anyone have confirmation that these are good quality?
Also, for a budget Qcopter, should i splurge and spend 10-15 apiece and get some turnigy escs or are these fine?

I had some of those ESCs and they are not very good if you flash them with simonk they will BURN it happened to 3 of the 4 I bought get some F-30 ESCs they are good and have nice pads if you ever want to use good software on them

I believe Alexinparis runs SS series HK ESC's, I have used the 8-10amp ones in my smaller quad, they seem fine to me.

reply may be late, but if you get the hk esc that says "card programmable", they are exactly the same as turnigy plush esc. they cost a little more than the SS non programmable one, but less than getting the original turnigy plush.
