I received my first meter just fine. Waiting on the second now. Unfortunately, USPS sucks. It might not be the seller. He has been very responsive to me.

Still waiting for my meter to re-ship.  Seller already missed two promised re-ship dates.  Paid on 2/12 with expedited shipping, so this is getting tiresome.  USPS would not seem to be part of the problem here.  >:(

*edit* Package now in transit again - fingers crossed.

Also.  It seems google has been thinking about all the tracking people are doing on their packages.  When I put "usps tracking" into google search, the very first thing that shows up in the results page is the applet? to paste the tracking number.  Paste the number in the text window, Track Via USPS button turns blue, click it and it will take you to your package tracking on USPS website.

Google has thought about this for years.  You don't have to do any of that.  Just type (or paste) the tracking number directly into the search box of your browser, if you're configured to use either Google or DuckDuckGo.  If you use Chrome, just type/enter the number directly into the "onebar" or whatever it's called.

You'll then directly be taken to the tracking page.  Doesn't matter if it's UPS, USPS, FedEx, DHL, perhaps others.  Saves a few clicks from what you're doing and you don't need to know the shipper.

I just looked on the Keysight website but I can't find any firmware listings or downloads for the U1252B, interesting that my Agilent-branded, 2014 Cal-date meter has the same software vn as later Keysight-branded ones.
I'd like to make the world a better place but they won't give me the source code

IIRC, the U1250 series meters aren't updated by the customer. The U1253B had a customer-installable update, but it was a change to an EEPROM value via software tool, not firmware.

Seller came through for me - arrived today.   :-+

Agilent branded with May 2013 cal cert.  Box/accessories/meter appear brand new and never touched.  Charging battery now.

I removed the large rectangular LCD protector obviously intended only for shipping.  Is there a second sturdier LCD protector underneath that shipping one?  Seem to have a 4mm bubble or blister on the screen that can be pressed down, but pops back up momentarily.  I can live with it - not sure I want to start lifting what might NOT be an LCD protector and regret it later.

I gues sthe seller, or USPS, has sorted his delivery issues out.

International shipping is, ahem, somewhat different - still waiting for mine. It appears to have reached the UK but once again we have the final courier tracking it as "label generated" but not on the move.

I hope it does not go missing

At least we can't blame this one on the vendor   :-\

Finally arrived  :-+ :)

3 and a half weeks and one lost to the USPS.

Aug 2013 cal, Agilent branded with v 217 firmware. Newer would have been nice as there will be no manufacturer warranty left but I'm not complaining. Not much point in registering with Keysight.

Accuracy seems fine, it agrees (to the last digit) with my Keithley 2015 that my DMMCheck has drifted high (currently measuring 5.0012V), it looks as though the Tenma 72-7732A that I bought from Top Loser is reading a bit low at 4.996V (though technically still within spec which is 0.05% plus 5 counts).

The included power supply (24V @ 2.5A) appears to be total overkill for charging a 250mAh 8.4V NiMH battery, and who thought having the PSU plug into the current range was a good idea?

Packing similar to everyone else, in my case a sad bit of bubble wrap inside the USPS box which was insufficient to stop the Agilent box from moving around.

On batteries:

The (unsealed/uninstalled) white Powerex 7.2V 300mAh battery included with my May 2013 meter charged quickly in the meter but did not indicate 100% on the bar graph.  Lasted <2hrs of continuous use.  Ordered an Ansmann 6F22 8.4V 300mAh low discharge replacement, figuring the original was done.

Charged the Powerex again, and this time it took significantly longer and the bar graph indicated 100%.  Battery never got warm during charge.  I defeated the auto power off and got ~40hrs of continuous use.  When the bar graph reached ~50% the low battery symbol started to flash and very quickly thereafter the meter powered off.

I'll see how much run time the new Ansmann provides.  The low discharge chemistry will be nice.  There is a setup setting to choose between 8.4V and 7.2V battery types.

So, cycle the included battery a few times, just like the manual says, before you rush out and buy a new battery for your U1252B!

*edit* Just noticed towards the end of the third Powerex charge the battery surface temperature was a toasty 48C.

Easier to just replace w/ new. No second guessing.

Indeed.  New Ansmann battery is charging now to top it off.  I expect this one to also get warm.  Now I have a backup battery in the Powerex.

I just leave the one it came with on. Cut around the screen with an x-acto blade in the gap between the screen and case to remove the overhang. My 20+ year old Fluke 87 still has the screen protector on that it shipped with.

Use smart phone screen protector, so many types, they're quite large and can be trim to fit it perfectly.

My fav is the hazy non reflective one.

Yes, smartphone screen protector. Get a big one to protect two DMMs. What? Don't have two DMMs? How can that be?

HRC fuses are expensive. There is at least one multi-page thread on here just about the cost of multimeter fuses…
