Kotto Solder Sucker, Vacuum Desoldering Pump Aluminum Body with Silicone Tip, Removal Hand Tool for Soldering Welding for Students, Engineers and Hobbyists

Perfect. Works well.

Works great!

very nice. Much better than plastic solder suckers

I was very pleasantly surprised. It works as well, if not better, than any other manual solder sucker I’ve used. It comes with two replacement tubes that can be cut to size. The tubes can gum up if you use a lot of flux but that is to be expected.I ordered some additional tubes from a different vendor. It was a pack of twenty for a few bucks, so I should be set for a long time. I’ve also heard some buy tubing from an aquarium store and used it with success.There has been mention of the stem breaking when depressed. It feels very solid, but I think I can see where it might snap in time with heavy use. But again, it feels very solid and I’ve been using it often with no issues. I’ve had great experiences using this in conjunction with a soldering iron as well as a hot air soldering station.The suction is great, and the unit feels well built. In my humble opinion, it seems every bit as good as the Engineer brand. The body is metal and seems very durable and substantial without being too heavy. I would buy this again in the future and recommend it to friends.I have had great luck with KOTTO products so far. I ordered one of the square desktop versions of their fume extractor and I was also pleasantly surprised. It is very effective for what it is and is very well built.KOTTO, so far, is a brand that I have come to respect. Hopefully that continues.About the rating:I gave it a five-star review because I couldn’t really find a reason to deduct any. It’s solid and does exactly what a solder sucker should do. If you’re having issues, you might just need a bit of practice. No shame in that.Thanks for your time,LLAP

Very nice size, well constructed! Functions well.

Works as expected

I attached an image showing the differences between the Engineer Solder Sucker and the Kotto Solder Sucker. It should be obvious which is which.Shorter spring Engineer.Longer spring Kotto.Shorter pump assembly Engineer.Longer pump assembly Kotto.Shorter housing Engineer.Longer housing Kotto.Having went through and broken 3 Engineer solder suckers I can say the Kotto appears to be better made.Two issues I have had several times on the Engineer suckers has been the top plunger area having too small a diameter of metal (causing breakage). Notice the Kotto sucker has a much bigger diameter base in this area. Its 3.4mm (Kotto) vs 2.4mm (Engineer). For the Kotto it seems like the diameter is larger than it appears in the photos of the sale page (perhaps it was updated at some point).Next notice the the metal shaft on the Engineer solder sucker is bent (this is a common issue). The Koto shaft seems to be made in a better fashion (it also appears to be made of a better metal).From the apparent quality I am already satisfied, but I will update this over time if there are and relevant issues.For those that don't know this type of desoldering pump is ideal for SMD retouching and requires silicone tubing (which adds up). However, there is nothing better for pulling solder out of tight areas (even professional desoldering stations aren't as good in many situations). Add fresh solder to the area, then while heating the solder place the silicone nozzle over the pool of solder and press the button. It takes some practice but the pump is so powerful there is a lot of room for error.

TL;DR:The KOTTO Solder Sucker provides efficient desoldering capabilities, making it a valuable tool for electronics enthusiasts. Its lightweight and ergonomic design, coupled with its strong suction power, enable easy removal of solder. However, the build quality could be improved to ensure long-term durability.Review:The KOTTO Solder Sucker is a desoldering tool that offers efficient performance for removing solder in electronic projects.One of the standout features of this tool is its strong suction power, which allows for effective removal of solder from circuit boards and components. The suction is reliable and can help quickly clear solder joints, making the desoldering process more efficient.The lightweight and ergonomic design of the solder sucker contribute to its ease of use. It fits comfortably in hand, allowing for precise control and maneuverability during desoldering tasks. The simple operation makes it accessible even for beginners.However, it's important to note that the build quality of the KOTTO Solder Sucker could be improved. Some users have reported issues with the durability of certain components, such as the rubber tip or the plunger mechanism. While these issues may not affect the immediate performance, they can impact the long-term reliability of the tool.In summary, the KOTTO Solder Sucker is an efficient desoldering tool that provides strong suction power for effective solder removal. Its lightweight and ergonomic design make it easy to handle during desoldering tasks. However, the build quality could be improved to ensure long-term durability. It is a valuable tool for electronics enthusiasts and DIYers seeking reliable desoldering capabilities.Pros:- Strong suction power for efficient desoldering- Lightweight and ergonomic design for easy handling- Suitable for beginners- Effective in clearing solder jointsCons:- Build quality could be improved for long-term durability
