Poor manufacturing quality

I was looking for a pair of two way radio for the trip to Yellowstone with my son.  I pick up this unit via internet at amazon. Since I am not always in United States, I had my relative to receive the parcel and brought it to Asia to me.  When I received it, I tested it simply, and found one unit could not hear the other unit.  I plugged in the headset with microphone then they worked fine.  I decided one unit had dead build-in microphone.  Since I was out of the country, I did not want to return for warranty/repair/replacement.  I opened the bad unit.  There was not much I could do as the component were very tiny. I could not check the microphone directly as I dare not to take out the circuit board.  It was a NG unit with its build in microphone.  But at least it worked with external microphone.  Thus I did not want to take the risk to totally damage it in order to repair it.  However I could see the spot where I thought was the soldering points of the microphone.  These soldering points were not beautifully soldered.  Thus I took chance to re-solder them by using my soldering iron.  After I re-assembled the unit I found it worked fine.  So the problem were poor soldering points, which is not forgivable in today's manufacturing technology.  And I checked the label and found they were made in China.  Do not tell me that China has poorer quality.  Today almost all the Notebook PC are build in China and I don't see such problem.  I would like to say it is caused by management or lack of it.  One can always subcontract manufacturing job to where with lower labor cost.  But one needs to have good enough management to manage the quality.  I gave it two stars because they still work after my repairing effort.

Manufacturing defect.  The macro and wide angle lenses would not screw together.  The threads were all buggered up. Quality control issue.  Had to return it which was a hassle-free process with Amazon Prime.

After two or three uses, one of the two pans purchased developed "bubbles" between the teflon surface coating  and the underlying metal that suggests the metal was not prepared properly prior to application of the coating (i.e., it was contaminated). Two of the bubbles connect and extend about 1 cm across the surface, which makes the pan useless.  This is an indication of poor quality control.  These are very expensive - decent complete raclette sets are available on Amazon for a little more than the price of two of these.  As a result,I can see no excuse for the poor quality control during manufacturing that resulted in this defective unit.  .

This is my second item purchased. The manufacture quality of the light was poor. The housing was scratched and had residual glue at one end cap. Unlike the first light, this one was poorly manufactured. It is demerit to the slick design of the light. Disappointing!

Good design, poor quality control in manufacturing. Went together poorly, did not sit flat on floor, and was more difficult to assemble than it should have been.

Poor quality manufacturing, I had to work on the high side valve to get it to work someone started it in a bind and I had to remove it and put a little refrigerant oil on the threads to get it to work. The high side 36" hose would not start on the gauge, the seal was not all the way installed and was in a bind, had to remove and replace it, to get the line screwed on. I haven't used them as of yet, but would not recommend them for a professional AC person that had to depend on them performing every day. I forgot the high pressure knob did not have a screw in it, I had to find one to fix that. Other than that they are normal foreign made POS!!!

I got to use this ONE time and then the pins got bent making it unusable. Good concept, but poor manufacturing.

What should have been a 30 min at max to assemble, took 2 1/2 hours. The seat side rails were assembled wrong. I had to disassemble the seat and switch the side rails in order to assemble. I found that three of the holes were drilled at the wrong location  and the wrong angle so things did not line up. I had to drill these holes larger and at the correct angle. Poor factory quality control. Once put together, the bench seems of good quality and finish. I would not recommend this bench to anyone because of the assembly problems.

The manufacturing is so poor, the screen prints (sublimation?) on some of the bands are already coming off IN THE PACKAGE - haven't even opened them up yet - going straight back.

Poor quality construction, when I cut for length, threading would loosen stones and they drop off. I will never use this product again.

Very poor quality control. Poor manufacturing, I received my equipment with a lot of manufacturing defects and damages. Big disappointment too bulky to return and very inconvenient. Dont buy!

The workmanship of this product is very poor and the quality of materials used are subpar. The product broke after 3 uses.  Amazon would not allow me post the truth about the product and my overall disappointing experience with the product, and Amazon.

As many of the other reviews describe, the manufacturing quality of this stand is pretty horrendous: Much of the metal on the drawer tracks are bent (one which shipped un-welded) and the drawer itself had one side welded slightly crooked such that it was wider than the front of the stand making it impossible to pull out after you have forced it closed.  I took a file to the protruding part of the drawer and shaved it down to the width of the other (properly attached) side.  I then used a soldering iron to solder the part of the drawer track which was unattached to the place where it should have been welded.  These modifications made, the stand works well and the drawer is functional (although slightly flimsy).  I place my Dell Adamo in the drawer, my LCD screen on top, and my peripherals (ext hdd, tv tuner, etc) underneath for a VERY organized workspace.  After a lot of looking, I have found this to be the best DESIGNED monitor stand, if only it could have been better made...

Quality control was lacking. The internals were glued together. I managed to fix it (with some heat and a vice) but I shouldn't have to do that.

Very poor quality control of the molded top and bottom parts of the kennel.  Top part does not line up well with the bottom piece guide areas and consequently does not slide onto the bottom as easily as demonstrated in the manufacturer's video.  The bolt holes for the four bolts securing the top to the bottom sections don't line up without considerable persuasion while inserting the bolts.  Plastic wing nuts are used on the metal bolts to secure the top and bottom sections, so real care is required to avoid stripping the wing nuts (the assembly instructions do say to hand-tighten only, but these four securing areas do seem rather flimsy).  I would think metal reinforcing flange rings or metal washer inserts on the top and bottom sections where the bolts are inserted, coupled with both metal bolts and wing nuts to secure these sections, would have made for a more robust product.

several screws stripped, and 2 of the rollers  will not stay in the bar. Very poor manufacturing..

After having read the reviews I have to agree with everyone who had a problem setting up the 183 tenoning jig and complained about the quality.  I guess Delta's quality assurance personnel don't read the comments of their customers.  Although the packing oil/grease was annoying I wasn't pleased with their quality control.  The quality of the castings and the precision machining was not great.  I was unable to adjust the movable fence due to the fact that the casting was not properly machined.  This required filing on my part.  The knob that adjusts the fence actually hits the casting when in the 90-degree position.  Some of the hex screws were over tightened at the factory.  One screw came stripped.  The threaded hole for the handle that clamps the stock to the face of the jig was not machined with any sort of precision.  I originally thought the screw was bent in shipping until I removed it and found the machined hole out of alignment.  When I complained to Delta they told me to go to a service center.  I contacted one of the service centers and was told that if they got the product they would probably have it for about 30 days.  They additionally advised me to send it back to Amazon as defective rather than bringing it to them due to the fact that it was new.  After experiencing the quality of this item I was not going to try to repack it and risk getting another jig of the same or worse quality.  A product like this should come set up with the name of the person who inspected and aligned it.  Perhaps that would improve the quality.
