The A+ in the title is not my rating, its part of the model number However, If I were to give this unit a rating, I'd give it a B.

Amazon.com: Aoyue 2702A+ SMD Profesional Repair & Rework Station: Home Improvement

I just purchased an Aoyue 2702A+ rework station for performing minor rework at my job. Short review: Great $250 unit for home stuff or if you work for a small company and need it for minor rework. If you work for a large company with deep pockets or if you want something for an assembly line, get something else. First, this is what the box had in it (from memory): 1. Soldering station 2. Desoldering gun 3. Soldering iron with a smoke absorber YouTube - Aoyue 2702 Smoke absorber function (thats not my video) 4. Hot air gun 5. Stand for soldering iron 6. Springy holster to mount on the side of the unit to hold the desoldering gun 7. Holster to hold hot air gun already mounted upside down on the other side of the unit (easy to fix though) 8. Additional heating element for hot air gun 9. IC popper with a few different popper legs to swap out 10. About half a dozen hot air nozzles including a small 3ish mm circle, 5ish mm circle, and various sized square nozzles 11. Additional tips, filters, and cleaning apparatus for desoldering gun. The first thing I did after setting it up (there is a red screw on the bottom of the unit that must be removed prior to using! might be easy to miss) was try out the hot air gun as thats all that I really wanted out of the unit. I chose the smaller circular nozzle for the gun and tried to attach it. The nozzle slips over the end of the unit and you turn a screw to tighten it down. This is very difficult to do alone as you must hold the gun, turn the screw with a screwdriver, and hold the nut with wrench so it doesn't slip. I imagine that the more expensive units would capture the nut so that all you'd need is a screwdriver. I have no idea how I would do this if the nozzle was hot. I might be able to let the holster hold the gun while I use the screwdriver and hold the nut.... Anyway, once the nozzle was on there, I turned on the unit, set the air flow to about 30%, temp to 370 deg C, and popped off an 0805 cap lickety split! It does what I need it to do, and it heats up pretty quickly. I hit the off button and the pump went to 100% in a cooldown mode and continued displaying the temperature until it reached 100 deg C and shut off. I then tried the soldering iron. It heats up like a bat out of hell, 5 seconds or so from room temp to 370 deg C. I think this is faster than my MetCal iron heats up. The smoke absorber does make it a bit cumbersome to hold, and out of habit I hold my breath while I solder. If I can remove it without damaging it, I probably will take it off. As it is, the tip is pretty large compared to the tip on my MetCal so I'll probably use the Aoyue iron to desolder those pesky ground pins and the MetCal for just about everything else. I haven't tried the desoldering gun yet. I never found them to be that useful, but my boss told me to spend the extra$100 to get the unit with the desoldering tool.

Gripes:
1. Soldering iron temperature is measured in C. I'm used to F, but hell all I have to do is remember to set it to 370 instead of 700. While the iron is heating up, it says "h <current temp>" and when it reaches temp it says "H <current temp>". What is the h and H? When the hot air gun is heating up it uses c and C

2. Hot air gun is HUGE. I've seen a few hot air units and most of them have a gun this size. I don't like it. The one I used at my previous job was the size of a soldering iron (it was a Weller, don't remember model number). It didn't have nozzles to swap out so you only had a 3mm hole, but thats all you really need for most stuff I've found. However, I'll get used to it.

3. Desoldering gun and soldering iron use the same connector. Cant have them both connected. Doesn't bother me much though because I don't really need/want the desoldering gun. If I do start to like the desoldering gun, I still have a MetCal iron that I can do everything but desolder ground pins on through hole parts.

If I recall right, the Auyue 936 are 35W, and the Kada one above is 60W.
Are those max power really matter? I believe the ceramic heater maybe the same, it is just the AC/AC transformer power ratings are different (on DX web, some Kada user take it apart and found only a 30W transformer is used, how can they get 60W power from a 30W AC/AC transformer?). It shouldn't be too hard to hack a 35W unit to a 60W. Or am I wrong?

It worked well, removed the majority of the smoke
Remove the smoke is a major concern when using the solder iron.
but I didn't like it.
Is the smoke absorber tip a challenge to use the iron tip?
The product does look professional and nice.

In tight quarters, the smoke absorber could get in the way, but for the most part I think it would be OK.

Are you asking about Metcal warranty or Aoyue? When my Aoyue "failed" I was able to send it back to the seller on Amazon for them to check it out. They found no defect and sent it back. The next time it "failed" I let it sit for a while and tried it again and it worked. As someone else earlier in the thread suggested, it may have been something in the air pencil handle that overheated and it went into an overtemp safety mode.

If you were asking about Metcal's warranty, I would expect them to have a really good warranty. The problem with my (employing comapny's actually) Metcal was that the tip on it died. I bought a whole new Metcal unit and a replacement tip for the old one. Replaced the tip and it went back to working perfectly. I didn't look into trying to return the unit under warranty as it was relatively old.

I am glad to see both can be supported or covered by the supplier.

One other possibility could be just a lose solder joint, when the unit is hot, the contact is off, when it is cold, the contact is good. You probably can verify this theory by using another hot-air gun heat the whole unit up, or simply check the circuit boards on the unit see if there is some solder joint malfunction.
