***Note: Up-scaling production update***Due to the extremely high demand, I just can’t keep up working only by myself.Recently moved to a new bigger workshop.Hiring more people to help me out with the not critical parts of the build.I have been training them for the last few months already.The new production rate will be increasing by 5 fold.I’ll no longer let the leadtime drag longer than specified on the website.In order to keep the quality equal or better.I’m still the one that doing all the critical parts of the build, laser alignment,calibration, sealing the whole unit for waterproofing, ect… ***Note: The NGAL mk4 has a leadtime of about 16-24 weeks.***Please consider carefully when placing the order regarding the leadtime.Because the overwhelming number of orders recently,exceeded my monthly production capacity.And the need to fulfill existing back-orders ASAP.In order to keep the leadtime reasonable within an acceptable range.I can only accept a certain amount of new orders monthly.Thanks for your understanding. ***Note: 100% satisfaction warranty***All units sold through my website will be covered with100% satisfaction warranty.In case you don’t like the unit for whatever reason.I mean whatever reason, even the unit works perfectly.You can return it for money back.Please note that the shipping and a 5% sales fees are not refundable.Buy with confidence is part of my mission.
