      This iron works great. Just plug it in and it heats up fact. Iron is prep'd right out of the box. Easy fix.

      For the price and "abuse", it's hard to beat. I may have to replace it once or twice a year. No problem !

      Great soldering iron

      Overall: 5 out of 5

      this is the 3rd solder replacement tip assemble that I have bought, the other ones got broken by my misuse and an accident. It is so great to be able to buy the replacement instead of the complete solder unit. That is one of the reasons that I purchased this assemble. Great value, excellent quality but nothing last forever!

      2 years of good results

      Overall: 3.5 out of 5

      I have been using these replacement irons for 2 years at my repair shop. It stays on all day 5 days a week. I will get an average of 6 months before they fail. Not bad for $10.00. Yea I could spend $100.00 for Weller but these have worked fine for me.

      Worst Value

      Overall: 1 out of 5

      Iron burns out long before even one tip gets used up. Weak as water, too. Has to be cranked up to max temp to accomplish anything - burning it out even faster. Less heat just damages parts through heat transfer while you wait for it to do something. Not an all-day workhorse, has to be turned off ASAP to get any time out of it. Worst value I ever bought from MCM, very disappointing waste of money. Stay away from this one.

      irons burn out too soon

      Overall: 1.5 out of 5

      Had this unit for a few months now and I'm on the 5 th replacement iron. I don't leave it on any longer than I need thew iron to be hot. I replaced this iron a couple of months ago and again this iron is dead. I had the old tenma solder station and the irons on those would last for months at a time. I usually ended up replacing the tips on the 3-5 times before the iron would quit. It s time to find a quality and dependable solder station.
