Finally arrived just now in my office, going to assemble tonite. I purchased it last week (Wednesday), and they shipped using DHL. Purchase directly from factory instead of Maxline (Eagnas Online) due to cheap shipping cost (less than USD 170), similar shipping cost will need 60-90days if purchase via online (Maxline)
I would like to thank many experts here who contributed their opinion as like Pete_LSD, taneepak, etc. I have broke 3 cheap racquets at similar position (high-noon-disease or 12 o'clock position), while it was only less than 23-24lbs. So after applied some experts' opinion, now I can string at 26x28lbs without any problems on cheap racquets. I did Eagnas calibrator with tennis string for calibration the crank.
for express shipping cost only .... Maxline also quoted me, but express shipping is expensive than machine price, so buy directly from factory ..
