I got mine via DHL in 1 week, once shipped, but they let me wait 3 weeks before shipping, so 4 weeks at all.
Also i stressed in several messages that i wanted DHL, not other services...bcause i had bad experience with another company, where i paid and requested UPS service, and they shipped with China express..
So, IMHO i think they tend to ship with China express, and generally works, but monitoring services are not as reliable as big carriers and also you'll never have a phone number to call and someone to speak in your country, if something goes wrong. Well, this companies take responsability for this kind of shipping, so of your laser get lost, they refund you or send another one.
Of course i understand that big carriers are xpensive for them, but usually, i would prefer and expedited big carrier than an express cheap.
