Did I ever like this hot plate? No. I'm used to working on Corning units in professional labs that have chemical resistance, precise temp control, 550°C max temp, powerful incremental stirring, and LCD display.This unit has none of these things, and is quite frustrating to use.To start, the knobs mean basically nothing. The heating element is only slightly warm until you crank it to max at which point its ripping hot. The stirring is only slightly more incremental, and quite shockingly weak as hot plates go. It also developed an issue early on where I had to fiddle with the knobs for like 3 minutes to get it to actually start heating at all.The hot plate surface has very minimal chemical resistance, and was permanently discolored by 2M HCl. It also happens to be designed in a way that's very difficult to clean/maintenance.AND all 4 little rubber feet melted from the heat of the hot plate itself within a month.Despite all that, this little unit lasted 7 whole months of very constant hobby use, which exceeded my initial expectations. It probably could have lasted longer but a beaker of boiling piranha solution spilled all over it.. which finally killed it for good.That said, I became quite fond of this little thing over the months along with all its annoying quirks, and I admit I'll miss it. At the end of the day the low cost helps with the barrier of entry into hobby chemistry, and it always (eventually) got the job done. I highly recommend this unit if you want to get into hobby chemistry, but aren't sure how long the hobby is going to last.

This is a perfect budget stirrer hotplate, it will get the job done and done and done and done. I've put mine through its paces, and it seems no worse for wear! I would advise plugging this into a cheap wattage meter plug if you care about repeatability, though. Reading the input wattage can be MUCH more reproduceable than relying on the dial, especially in lower temperature ranges. The amount of dial-turn from 0 watts to 90 watts is quite small, and the give on the dial makes consistency difficult. That said, if you need a temperature controlled hotplate, this isn't that - so a bit of a moot point! It does what it's supposed to, very well, for a good price.

Muy bueno y económico. No calienta tanto

This is a great company who went above & beyond to make their customers happy. My first order had the little magnetic stirrers missing, they were on it to make it more then right & I am very happy with the product.
