I used this to drive a steam distillation on three occasions, running for 8-10 hours each occasion and the power intake burned out in the middle of my third run, the fuse is fine, but the actual power cord receptacle is toasted. Everything else seems fine, but getting a replacement power insert has been difficult as they all need to be shipped from China.But it's a very inexpensive mantle... It might be worth it if you don't need to run it as long?

This is the second product from this seller of the same item (one was the 500mL, this one the 1000mL) - both have had the mag stirrer fail after a couple of uses that didn't even exceed 130°C. The mag stirrer is an integral part of the heating mantle.

It’s slow to get to the set Temp but it is amazing once it does. I tried putting the probe In the vapour phase during a distillation and it actually managed to hold the vapour temp exactly at 78 or 79 as I wished when distilling ethanol. More amazing, once there was no more ethanol, it still managed to keep at that temp despite no 78 degree BP liquid which means it kept the water vapour front a millimetre below the probe! You can use without the prob but just stick it anywhere and use the temp control to adjust it. There is a A C and L control when holding down the set button but no manual explaining what that does! Worth the money

This mantle came with defective temperature controls. I have contacted the seller and will update this review accordingly.Update: it has been 2 weeks and the seller is not being very helpful with the attempted return for the defective item.

Seems to function well enough. I like the digital temp adjustment. It would be nice to have an idea of the rpm of the spin bar, but not necessary. Really that's the big downside so far. Also not being able to use the heat at all without the probe could render it useless easily enough. Maybe have an option to use without temp probe. It heats up fairly quickly though, compared to some others I've used. To adjust the temp you have to scroll up and down by single digits, which is slightly tedious. It's absolutely great for the price though. Wish the thermo probe was more readily available for replacements. Almost all the mantle/probe and 2 neck flasks are flawed the same way. The probe ports are angled in such a way that causes it to go straight in to contact the spin bar when fully submerged. Making it very difficult to run batches to completion. I usually just bend mine a skoach to get it past the spin bar. Which is great until you need to use a glass thermowell (you can't just bend them without proper experience). Joanlab actually sent me a replacement for free! Very cool of them. I wish they made the 500ml mantle just the same.
