I switched mine back to USPS Hong Kong. I'm in Chicagoland area. SG post took over 1 month on 3 packages then switched to HK and last HK order took 16 days from date of order placed. The HK package got here a week earlier than all 3 SG packages and order was placed a week after.
*no batteries or liquid in any of the packages. One SG package was only 2 drip tips.
