Scilogex Circular-top Digital Magnetic Hotplate Stirrer

I purchased three units: two used from Amazon Warehouse Deals (the sheer number of used customer returns for sale should be a red flag on its own), and one new sold by Amazon.Both one of the used units and the brand new unit I received were defective out of the box, as the stirring function did not work at all--it makes an electrical hum when turned on, but the bar does not move. While another used Warehouse Deals unit worked, it didn't even include a power cord in the box.The plate itself is so small as to barely be usable, the stirring function, when it works at all, yields wildly inconsistent and unstable speeds, and despite the product image, no sensor holder was included in either of the three boxes. In this respect, the main and only product image violates Amazon's product image rules, as many who answered a customer question indicated the product did include a sensor holder.Even though I received one working unit out of three, I will almost certainly return it because 1) the size and functionality are poor, and 2) there is no guarantee it won't stop working right after the return period.

Does a nice job of controlling temperature and stirring with minimal if any fussing around. I did note some negative reviews regarding the limited heating wattage. I use a 500ml Erlenmeyer flask and it gets as hot as I dial in the temp. With an open beaker you obviously lose more heat to the environment. Not appropriate for boiling the ocean (smile).IMHO the probe is not optional - it's a necessity. It allows me to measure and control to the liquid temp, not the plate temp.Controls are easy enough. Purchased with 213B2 Karter Scientific Glass, and Scienceware 371100118 PTFE Octagon Spinbar. Awesome combo!

After 1 day of use when i turned down the burner and allowed it to cool off i came back and the porcelain was popping off. Nothing more than 1 drop of water touched the hot plate. Half of the porcelain had cracked off! I wrote the manufacturer we will see what happens.This is unacceptable $260 down the drain.***UPDATE*** The manufacturer apologized saying this should not have happened and sent a brand new upgrade to stainless steel without any hassle at all. Replied same day on a Sunday night. Excellent customer service.

It often is 50c hotter than it should be. Mine has recently starting making a worry electrical hum. I will likely return it as soon as I have time to pack it up, since I no longer have the original packaging. As far as I am concerned this is no better than an magnetic stir plate, which could be had for $150 less. It's frankly awful, I just don't have the time to return it this week.

Very nice. I was a little worries about cost but knew the brand would carry it beyond the warranty.I've had this product for around a year and it's worn in great. The first few times I turned it on I could smell the oil and whatever else burn away and season. Now I smell no odor and it keeps temperature stable with or without the magnetic stir.

515 Watts should theoretically heat 1 L of water to boiling in 10 minutes. Of course there are losses; water evaporating from the beaker, convection from the sides... but some 40 minutes later and that liter is only at 80 C. There is also an annoying whine from the stir bar motor.Otherwise, seems like a nice little package for modest work. The sir bar magnet isn't weak, the controls are nice and easy, and the inclusion of the stand rod and thermometer make this worth the money for what is is.

This is a great little heat plate magnetic stirrer, got a great price also. It boils and stirs like a tornado has a large magnet stirrer with it.

I had a chinese made stirrer which burned up recently, so I replaced it with this unit. The controls are smooth, it holds temperature very well, and overall, its built very well.

Good quality
