Hello everyone, good day.
mid year sale has passed. and the price has returned to normal, if you want to know the next time to have big discount,please follow our shop and you can get the information at the first time.
here is our shop on Aliexpress:https://rdtech.aliexpress.com/store/923042
today let’s talk about our UM25C. It is developed based on UM24C.
UM25C link:https://www.aliexpress.com/item/32855845265.html?storeId=923042&spm=2114.12010615.8148356.11.245f65cbtu59BB
you can see the comparison chart here:

and it is recommend by many customers:
[This tester is a useful purchase for anyone who is a little fond of checking banks, testing wires and keeps the pulse on checking the characteristics of these devices. The tester embodies a wide range of capabilities: from checking wires, counting spent energy to kwh and mah, building graphs of energy consumption, transferring data to a computer and a phone (in a model with bluetooth), determines the type and potential of charging (fast, fast or other) and simply will not replace for almost all wires (except lightning). At a price, the offer is advantageous if you separately want to buy testers for usb, for type-c and micro-usb connectors. I advise you to purchase complete with hd35 load, as this will additionally allow you to test wires and plug-ins. In general, only with this load the test will be possible, and the tester itself will help to check the compliance with the declared characteristics of the seller. I’m happy with the purchase! Delivery took 10 days, the seller sociable, sent the goods the next day.]

[Received today a parcel in pavlodar. Got in record 18 days. The speed of delivery was pleasantly surprised, but here the foam container was something crumpled in the center. Thought it was all, ppc. Broke everything. At the autopsy, it turned out that fears are in vain. The controller board itself is visually not affected. Dimensions live, amaze with minimalism. I haven’t checked yet.

First, I will say that RD Tech makes great products.

However, these sales threads are very confusing and I have never been able to actually get the price that is posted in these threads.
It is usually either limited or restricted (new users only) coupon availability or the deal has expired.

Why not just simply offer a discount code for BLF members?

They offer discounts to BLF members.

Just send them a message to them before ordering a product, and they’ll try their best to give you a good deal.

That’s how I got a discount on the DPS5015 that I got last year.

Hi friend
