The Lasko Designer Series Oscillating Ceramic Heater with Remote Control is one of the top-performing heaters at two owner review sites, Amazon.com and Buzzillions.com. They say it's effective, stylish and quiet. The one professional review we found wasn't as positive, noting a lack of safety features and concluding that heat output is only "fairly good." The heater is comparatively inexpensive for an attractive unit (compared to the Dyson Hot + Cool AM04 (*Est. $400)), but it doesn't have the brawny heat output of some other units.
Performance doesn't suffer for style. The Lasko Designer Series Oscillating Ceramic Heater looks better than many alternatives, and reviewers say it doesn't sacrifice performance for style. We found only one professional review for the Lasko 6435 (Good Housekeeping), but in general, owners agree that it's very effective for heating a small, closed space. Its effectiveness in larger or more open rooms is debatable. Users also like that it oscillates and has a thermostat and timer, helping it heat evenly and consistently.
Remote control disappoints. The remote control, which ought to make this product easier to use, is a frustrating feature for many owners. They say the remote is difficult to read or use. However, other users say the thermostat and timer are so effective that the remote isn't necessary. The heater is lightweight, too, and arrives fully assembled.
Low marks for safety. According to Good Housekeeping, this heater can get very hot after it's been running for some time, plus it lacks a handle for carrying -- creating transport issues. Testers also say it lacks important safety features, like a tip-over switch, and that it's easy to knock over.
Unusually quiet. Users agree that this is one quiet space heater -- uncommon among heaters with fans. There are no noise complaints from owners with a properly functioning heater, though one user did have to exchange a unit that made a buzzing noise. No professional tests report on noise output from the Lasko 6435.
Review credibility: Very Good Few space heaters on Amazon.com receive a considerable number of reviews and maintain an average score of more than 4 stars. The Lasko 6435 is the only heater with more than 150 reviews and 4.5 stars. Some reviewers refer to this heater as a "powerhouse" and say it puts out an impressive amount of heat for its size; however most users say that it's best for a smaller room and can't heat large or open areas. Reviewers praise the timer and oscillation, and they say the design is stylish. Some users do note design flaws with the remote, though, saying it's difficult to read or to press the buttons.

2. Good Housekeeping
Review credibility: Good Good Housekeeping gives the Lasko Designer Series Oscillating Ceramic Heater with Remote a score of B overall. Testers found that this heater does "a fairly good job of heating" and distributing heat evenly. They also say it's lightweight and easy to use, though the lack of a handle makes transporting it difficult. The 6435 also gets knocked for how easily it tips over and the corresponding lack of a tip-over switch. Editors also say the surface can get hot when it's been running for a while.
