Anyone try it yet? I want to build this into my maintenance schedule and do it at certain intervals but haven't heard too many people using it. Anyone with first hand experience? And what is the difference between the two items below?

I tried it and did not change the status of my DPF, but later I found DPF had mechanical damage. Few youtube reviews show it working if you have small clog.
Beware that LM advise use of their very expensive injector (I used garden sprayer) and you should use 2 chemicals in 1 process.
But why you wont to go for extra cleaning? Isn't normal regeneration on your car working?

I believe normal regeneration is working but around los angeles, having a 20 minutes or longer drive at above 50mph is a rarity. Thus, I surmised that my DPF can't be doing very well at this point. I'm at about 90K miles now.

Do you have system monitor?
We drive mostly 10 miles routes in the city, yet when I see regeneration pending, I take extra loop to not abort it.
Takes about 10 miles of city driving. Strangely car will do ECO shut-downs with pending regeneration, so I turn it off to speed the process.

Don't have one but this should do the trick. I'll purchase at some point. Is this the one you use?

ScanGauge is convenient as it can be left plug permanently, but is costly. This 1 is cheaper, but more hassle. I have both

have you compared results and how well do you like this?

They are different animals, so depends what you do.
I like ScanGauge permanently plug in on my trips, so I can observe DPF status, DEF status (it seems pretty crucial on Sprinters) and even load status.
It will also show selected gear on my 2015 Sprinter, who doesn't have it on the cluster and that when towing can be crucial information.
Autotel has more options for troubleshooting and adaptations, but my Benzies run pretty good lately, so beside some testing, I did not use it much.

I am very sceptical about whether these actually work.

On the face of it it gets diluted 100 times over when you put it in a full tank of fuel and then it gets burnt to toast during combustion, can it really then dislodge carbon build up after all that ?

Interested if anyone has actually perceived noticeable improvement in their car after using it and if so which brand

?
what is that having to do with my quoted reply?.
I will repeat my old advise, that driving diesel with monitoring scanner can avoid lot of problems.
Since the old reply, I have AEM done on my Bluetecs and having warranty, I am putting them to additional test.
So regeneration aborted in city driving, will resume next day once engine reaches 60C.
When we drive only about 6000 miles a year on our sedan, it did not see long freeway trip for about 3 years, when our city driving is about 50% streets and 50% short jumps on freeway.
