Soldering is weak, breaks easily.

My daughter ordered this some time ago and just told me that it broke the first week she had it.  I wish she had told me sooner so we could return it.

I purchased this item to remove roofing tape adhesive from metal surfaces. Item worked well for 20min then unexpectedly the corner of the razor blade snapped. This caused a flash of light and an electrical short in the iron. The iron does not heat up anymore. The screw for interchanging tips kept backing out during the short time I was scraping. I'm disappointed this tool broke so easily. I hope to move the tip to another iron.

Solder sucker blows apart when used. Reassembled it and same problem.  Poor quality.

The electrical qualities of this unit are irrelevant, as its build quality is so poor that you're likely to break it during installation. The use of screw terminals was a bad design choice, as most users of this device are going to need to splice into something and will need wire leads. I ended up cutting and stripping several 9-inch leads out of the blue "remote turn on" wire that comes with amp kits. Unfortunately this was for naught as the screw terminals are extremely easy to strip and there appeared to be no amount of torquing that was enough to hold the wires but that did not strip the block. If you are going to use this unit, expect that you may need to solder your leads onto the terminal block.

I ended up picking up a&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/PAC-SOEM-4/dp/B002XW2IC6/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">PAC SOEM-4</a>&nbsp;which did the job. It was a little bit bigger, but had built-in leads.

I ordered four of these to use with my desktop and my mixer board, and three of them have broken. The point of failure seems to be the textured metal part encircling the jack, which on all three has split open just enough on the 3.5mm jack end to allow the whole jack assembly to fall apart. The 1/4 inch plug is otherwise fine, but it is completely unusable once that ring splits open.

Additionally, the gold color on all of them has faded or perhaps tarnished to a much darker color.

The first time I used it in soldering it broke in half and kept breaking into smaller pieces every time I silver soldering.

Like the other one star reviews here, the RCA wire came un-soldered at the RCA jack.  It was a ball of solder that just broke off (never bonded).  Looks fancy in pics, but cheap feeling (and performing) in hand.....  Regrets....  Should have spent more on a better brand.

The center lead and ground of the cable at the SMA end is not soldered nor secured in any way. With just a slight bit of pressure, the lead will pull out of the connector and if you don't realize this and transmit, you might damage your radio. I've discontinued using it until I can permanently secure the connector. Very disappointed in the quality of this adapter.

Used 2 of these to split the 2-channel input signal into a 4-channel amp. Working perfectly. Unfortunately the metal is so thin that the contacts are made of that they break easily if bumped against something.

I was given this kit as a gift and the quality is very lacking. the soldering iron tip broke off after about 2 days of use, the wire strippers are so cheaply made out of 2 pieces of die cast metal they fail to strip any gauges i have come across. all the metal parts have rusted. you can get a much better kit for less. don't overpay.

broke easy..i love the design because i like tinker but the quality is not good.

I am a MECP Certified mobile electronics installer and electrical engineering student and bought this soldering gun to use for work and hobby use, after using it about 5 times the tip would beat up but not enough to even melt solder, very disappointed in the lack of quality. Even more disappointing is that when I tried to return the item because it's lack of function I was informed I was 1 day outside of the return policy. Don't buy if you want to use more than a couple of times.

Ok product, worked well until it broke. Took it apart and the wire that goes around the doorknob was poorly soldered and not braced adequately to hold up to normal use. Resoldered and braced and it continued to work for a couple of weeks then died entirely. Will not buy another.

Works, but is way too fragile.  I have had this for less than 4 months.  It connects with other Bluetooth devices easily.  It was easy to install.  I only gave it two stars because while plugging in a flash drive in the USB drive above the one this was plugged in, the top part of the black back end broke off.  It didn't fall down or get hit, just came right off.  It exposes what looks like a computer chip, and does not snap back in.  I am concerned I about the life of this product now that that part came off.

The wires for the power and antenna are thin cheep and break easily.

Very unhappy with the product due to how fragile it was. I attempted to uncouple the main part from the plug but due to the magnet being too strong and the flimsy plastic being too thin, the transmitter broke in half instead. I put it back together but after a few days the wires broke off of their solder joints as well. It worked great right up until it broke in half.

It worked great about 5 times, then the switch broke off the next time I turned it on. The inside of the switch is super cheep plastic. It will fail.
