abunda_amazon_reviews This solder's strong point is also it's weak point in my opinion. I've been soldering daily for a long time and have used various kinds of solder (lead free at work). I typically use leaded solder at home. This was my first roll of kester. I have to say, it solders wonderfully, though no better than other quality leaded solders i have used. The thing is, clean up of the flux is a nightmare. It turns into a hardened gooey mess and cleaning takes 3-4 sessions of scrubbing and blowing off before things are cleaned up. I would call it abnormally difficult to get clean, in fact. Now you could say, it's no clean, leave it alone.... Each to their own, but that's just half-assed imo :). The job is done when it looks stock and it's clean.;;Reviewed in the United States on October 18, 2018;;3.0 out of 5 stars;;Holy flux..;;ben;;;Have you ever wanted to solder micro PCB transistors and resistors like a demi god/ robot? Then this solder is for you. Do you want a lead solder with a competent flux that will bond your connections like a champ, and give off fumes with the sweet taste of Bismuth salts and antimony that pairs nicely with a glass of Montepulciano or a Sanghiovese? Then this flux core is for you. Do you want to live as long as possible and keep your sperm count up? Then maybe you'd prefer a Rohs solder, and after throwing it across the room you'll realize: laboratories and electronics are not for you. We all die sometime, we're surrounded by death. No need for the constant reminder from our electronic devices that die before their time, due to inferior Rohs compliant solders. Women like mysterious dangerous men, and what could be more dangerous than a man who breathes fire and lead fumes? Nothing. Take it from me: a scientist; put a roll of this bad boy in your laboratory and watch the panties drop. Now I know what you're thinking: "we have a disparity in the sciences, with too few women taking degrees in the hard sciences thanks to years of uninformed dogmatic gender role ascribing women to careers other than the hard sciences. Now we're paying the price. Do you realize how hard it is to get a lady in your laboratory?" Well, true. And no. I don't. because I use spools of lead solder. Fact: women are drawn to the sweet smell of Bismuth salts and the pheromones excreted by a man with acute lead toxicity coursing through his veins are unmistakably unique. It intoxicates their senses, they're drawn on a genetic level to procreate with you *immediately* because, with lead, there might not be much more time. Pretty sure Darwin mentions the mechanics of this exact biological drive in his work "The Expression of the Emotions in Man and Animals" but I wouldn't know. I'm a real scientist, not a biologist so I've not the time to read such quackery. What I do know about women I've learned from observation and captain Kirk. From observation I can assure you, heat up some of this solder, sit back and watch the women come in droves. Your lab will make Hugh's house look an all boy's academy. Hang another roll from your review mirror. Trust me. This solder will save us from the gender disparity in the sciences. It will save future generations. But, don't wait, copulate. After all, it is lead bearing solder, so there's not much time. I will continue to buy this solder.;;Reviewed in the United States on June 10, 2014;;5.0 out of 5 stars;;Plumbum.... A "other Metal" by any other name would smell just as sweet.;;Spukhafte;;;Solder is great, but a piece of fiber-reinforced shipping tape is wrapped around the product to keep the cardboard attached during shipping, and the tape can't be removed without damaging the product label which contains all the important data such as the Kester brand name, SN63 PB37 tin/lead ratio, 3.3% rosin core, and manufacture date. I work with multiple rolls of different types of solder, and I prefer that they all have their product labels intact so I can tell them apart and order the same type again when I run out.;;Reviewed in the United States on October 25, 2018;;3.0 out of 5 stars;;Tape removes product label;;The Engineer Critic;;;So, I had been building electronics, fixing guitars, doing synth work for two decades before I switched to this stuff from various generic other solders (whatever the store had on hand). All I can say is that I would have saved myself some time and work if I had used this and a temp regulated iron from the beginning. It's night and day, life changing, hours saving, and more satisfying in the end (turns out my soldering tech isn't as bad as I had always thought it was. Switch to good tools and I get a solid, good-looking joint every time). I have also tested this with a good quality (goot) non-temp-regulated iron and it's still very good. Just, learn from someone else and buy great tools from the outset or don't solder. Soldering is a way more fun and easy experience with the right tools. This solder is one of those right tools. I don't really see how you could do much better than Kester 44 if you're buying electrical solder in this spec. So, I'm giving it five stars all around.;;Reviewed in the United States on August 27, 2019;;5.0 out of 5 stars;;Just get this solder and use it.;;J. Pratt;;;This is reallly really good. I made the mistake of picking up some generic cheap 63/37 Chinese solder, thinking "63/37 is just two elements, it's must be all the same". That was wrong, it just simply liquefy like good solder should. This solder does. It's the good stuff, and you get sooo much that it's actually cheaper than the "cheap" stuff.;;Reviewed in the United States on March 23, 2018;;5.0 out of 5 stars;;This is the good stuff;;Mark P Jung;;;This is the only brand of solder I use for my electronic builds and repairs. I like this formula of mix, seems to flow better than the typical 60/40. Also so do yourself a favor and don’t buy the cheap stuff from China, spend a little more and get quality.;;Reviewed in the United States on November 15, 2017;;5.0 out of 5 stars;;Electronic solder;;S. P. Shute;;;I'm not an expert, all I did was reading reviews and watching training videos before picking this brand, type, and diameter of soldering wire. Kester seems to be pretty much the industry standard, or up there with few others, and my experience so far has met those expectations. With a bit of trial&error, I realized that my soldering iron was hotter than it needed to be. I turned it down a notch, and now things work much better: good solders, iron tip stays tinned and doesn't oxidize as quickly, and almost no smoke. At these lower temperatures, I kind of like the smell of the core flux vapors! If the core flux get hot enough to burn, then, yeah, that acrid smoke is really nasty.;;Reviewed in the United States on June 24, 2017;;5.0 out of 5 stars;;Works great;;Busygeek;;;A mouse ate the wiring harness on my three year old washing machine and no factory replacement harness available. So I ordered a Hakko soldering station, some silicone voltage rated wire and this solder to repair the eaten up sections of wire. (The mouse was very hungry). I'm an old electrician who had been certified for NASA quality solder connections doing mil-spec work so this was a pretty easy repair on a three year old $1500 washing machine.;;Reviewed in the United States on November 30, 2018;;5.0 out of 5 stars;;Good stuff for electrical/electronics work.;;D.
