So, other than a slow leak from the connectors(?) what is wrong with it? Was it accurate for pressure reading versus something more expensive? Did the temp clamps perform comparatively to more expensive units? Would have been more interesting. Obviously these are no good for leak testing after vacuuming but could be useful as a cheapo set for charging.
Woooo. Totally "You get what you pay for". No FUN there. You can get them for 60 € in Ali Express. Was actually thinking about getting one. I think I'll save up for a Testo . Thanks for the video.
Haha, I bought the manifold for the fun button to,off ebay. First it was a week late. Then I finally got to test them against my Testo manifold today. The clamp on sensors failed in the first 10 minutes. Won't even read the t1 sensor . Major regret.
what made you get those manifold risky man, ? your fieldpiece srl8 have you changed the heated diode refi sensor,my srl8 worked real good but lately its been erratic and weak seem like it cant pickup the refri I m guessing the heated diode needs replacement what your opinion!
For as cheap as the company I work for is, they give us fieldpiece electronic gauges. I've loved them so far, only shucks is it doesn't have a pressure test timer..unless I haven't found it. Otherwise I dig getting SH and SC readings, or not earballing it for a vacuum. I know one thing, I'm going to make sure my boss doesn't find those gauges. He would be that guy to do that.
It's show time, don't let me down DOYs. Those wheel knobs are so pimped out. Watch out testo here come the DOYs😂 Dr. Kevorkian gauges of choice. Great one Dave😹👍
the cheapness reminds me of those plastic safe "tools" the various manufactures of power tools puts out for kids. This could be a part of the lil' kids refrigeration tech test set.
Thanks for the review! I saw these on eBay and was terrified at the thought of some poor tech using one in the field. I am looking to make the jump to digital mainly for 410A. I'm on a budget so I was thinking the testo 550 may be a good start.
Look more like Testicools hahaha! On a serious note, be careful of the sight glass, mate of mine had one (on proper brand manifold) fail and hit him in the face...
hehe, chinesium fighting chinesium gotta love it!!! (none win in the end) pull out the 30+ year old gauges with dry-rotted outer hose jackets..... aka, only thing needed?, eyes to see the gauges, scribble stick, touch and something to scribble on if you wanted to do math ;)
The knockoffs often have the last laugh as they often reinvest the original sucker purchases to improve the product up to a point as to threaten name brands.
warning : they changed the name to Beley autool on amazon.. exact same tool.. this video is great for warning people about the shoddy shite some companies sell
i have the exact same unit, and yes it's plastic but it's HEAVY. Feels like some decent mental internals based just on weight. The plastic COVER is cheap, but the innards are what matters.
Oooh! It's got a setting for R-744! Now *that* might result in some "fun" shrapnel! I've seen some much more convincing knockoffs of the Testo gauge set on eBay. I think they're too expensive to be worth the risk. I'll wait until I can have the genuine article.
Probably worth $20usd in Mainland China. Tools and equipment is super cheap over there. But the quality is questionable 50% of the time. The mechanical tools are okay. Bought some while I was there for training and use them as #sharetools Lol.
It appeared to do the job. I checked and they had their own version for temp probes. Yeah its cheap. If you're a pro its shameful to have cheap tools so why buy it? How is it for a back yard mechanic that does a few ac units or the occasional heat pump top off? After all that's probably the real market I would assume.
That's my question too. Build quality aside, do they function well? I do maybe 20 automotive a/c systems a year and can't justify spending big bucks on Testo etc, but I'd love to stop using analog gauges and go digital.
lol. I boiught this device as i newbie. Please, tell me how to use this fucking device? It is always shows different numbers. In what order to connect it? Power on, Zero, connect hoses and then Open valves?
Will there be any serious Professional, who can give a recommendation on the quality of this equipment? And that he can talk about precision and accuracy in reference to standardized patterns of both Pressure, temperature and other indirect variables? I say this because we must make serious analyzes with arguments that estimate the Cost-Quality factors without prejudice to "Brands" or Nationalities. We would do a great favor and contribution to the Engineers and Technicians who are looking for fair cost alternatives. Thank you......
What was this some type of Amber alert for the industry? Caution cheapo don’t even think about it. Nor-Cal Dave and America’s Test Kitchen the tech edition. You can’t even give that thing away! Bad JuJu. Contact Amazon, they’ll give you your money back.
Yeah, America's test kitchen convinced me that I needed to spend $80 for a Thermapen kitchen thermometer. Reads in 1/4 the time of my previous digital thermometer off of Amazon, which is really important when you're standing in front of a 400 degree oven. Plus it comes with a calibration certificate traceable to NIST.

Many Chinese knock off with cheap plastic but good inside. Why would you buy it if you don't use it? I am fine with this because i don't do AC repair for a living. If I do i would spend the bucks for the pro. one. To me Fieldpiece brand is pricey but Testo will be just as good but way more reasonable price.
well, they found a use for the billions of ancient stockpiled junk s-video connectors :))) en.wikipedia.org/wiki/S-Video IRL, the anti-idiocy pin looks different size.... but a mini-din jack/plug none-the-less
I really don't understand your complaints. This unit is like 5 to 6 times cheaper than Testo. Why would you compare them? What is the reason to do that? Kinda stupid:)

Your review sucks! Aside from the "cheap plastic" you didn't state why it sucks, do the measurements come out correctly? Was there a problem with the device other than it doesn't zero because you modify the knob? Can't just say sucks and doesn't have anything to back it up. Also "Fun" mean function.
Modified it came stripped it’s a straight piece of shit. Leaks and is not worth 20$ fact. Go re watch and report back. Pay attention this time. And don’t skip the Commercials, I’m trying to put a kid through college.
This veers on off-color, but the person criticizing the way you reviewed the cheap Chinese manifold has a username of Riceball 4U. I'm not trying to be racist, but that's funny. Imagine if you critiqued a German-built set of Testos and user BRATWURST 4U starting getting up in your grill. Funny!
You are untitled to your opinion. Here's the thing with this product. It's a DLG D1- 517 DIGITAL MANIFOLD. This product was tested and a product of Digital instruments a very well know testing company. The products you tell everyone to buy are also tested by drum roll please. Digital instruments. Now to be honest I've not seen Duoy! Where DLG logo is located. You may want to research before putting this product down due to a possible knock off out there to this product. Now my question to you is why say it's a novelty thing you just had to have then actually used it on a job? If it didn't work on the job site then maybe it's because you yourself said you MODIFIED IT! how you accomplished this is very questionable. I have been in this trade for 39 years now and have seen it all, but never have seen someone so hard to put a product down without proper research. Do your Research on Digital instruments and go ahead and put this technology company down. If there's a knock off then say that before you put down the very corporation that checked every single product you mentioned and recomendaciones on buying. And because there's a fun button that is featured does not by any means make it junk. You sir are not qualified to modify or use defamation towards a company product. Anyone that takes your word on this is actually more dangerous then any trained technician.
That product is low quality. It came stripped out and sucks. I purchased it with my hard earned money 💰 and I’m doing the HVAC /R service technicians a favor by telling them not to waste there money on a poor quality gauge. Maybe you should step your game up and make a better product, because this product is terrible. Nothing was modified I had to put the knob back on that came stripped out right out of the box. Junk is junk. And they leak. Oh and I’m qualified to do this. Look 👀 close 🖕🖕🖕. 🤣😂🤣😂🤣😂🤣😂🤣😂🤣😂🤣😂🤣
No your not qualified to open and modify anything other then calibration to zero out you manifold set. Your take away from this is it's junk. No problem at all and to each their own as you could say about any equipment. But to say it's a dangerous product is also saying that any product that is digital to be junk if going through digital instruments. Pretty big statement. Well having said that any products your recommend are run through this company so what's that say about you analysis.
Merchant your in outer space. The product was never modified. It’s construction is cheap, and it’s a terrible product. The best product available ever made is the ultra pleasure vibe 2000. Now with rechargeable batteries 🔋. Bzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz
