Question: How many prongs does the cord have? This is for my office and we can only use 3 prong heaters.
Document: Needed a heater for my son's room. The smallest room of the upstairs and it gets cooler than the others at night. He still is a baby and doesn't use a blanket correctly. Anyhow, after researching many heaters, I decided on this one.
This little heater is great. Bought it for my office that was 49-53 degrees every morning and it heats it up to a comfortable 65-70 in about 2-3 hours. I only wish the height was adjustable - my toes are still cold. =)
I went through a ton of these reviews on different heaters and one concern I saw in a bunch of them was that the power cord might not hold up (i.e. cause electrical fire).
This heater works great. The quality of heaters today just suck. Ive been through so many. But this one has lasted this far and I havent had any problems with it over heating or just not clicking on.
This heater works great! Now I have to give a little disclaimer: I don't have much experience with many different brands or types of space heaters. I do know however that this space heater kept a 20'x25' room at 85 degrees no problem.
And two fan speeds to go with that - the fans runs more slowly and quieter on low - which is a feature that's missing on many heaters for some inexplicable reason.- Quiet for a heater with a fan, especially on the low setting. (But that can't be used with the auto thermostat setting, see below!
I kept borrowing one of my employee's space heaters for my office on weekends, and that was making me look like a heartless boss when I would forget to return it on Monday, so I did a little research and purchased this one from Amazon.The other heater was a small 1500 watt unit, which is the same wattage as this one, but this one throws out far more heat.
We have had no issues. I am about to buy 3 more because we fight over which rooms get these. My favorite things about these heaters are: (1) they are very quiet, (2) the timer feature, (3) physically do not seem to get hot like other heaters, (4) pedestal design gets the heat where you want it, (5) they work - they heat a good sized bedroom. We've had no problems with either unit.
I bought two of these along with a few oil-filled radiant heaters and a Lasko tower heater. Both of the pedestal heaters died after the warranty was up, but all the other heaters are still going after 3 years. In general, Lasko is a pretty good brand, but these are junk. They work well at first, but after a few months don't put out the heat as well -- even after cleaning them out with compressed air and a vacuum. One of them actually melted my outlet.
This is just a review on the manufacturer-Lasko. Over the years I have bought 2 Lasko model 6350 heaters-very similiar to the 5365. I paid $50 at Target for them. One heater was bought for my girlfriend 3 years ago. She has used it heavily as a supplement to heat a bath/closet/single room area and it has worked great. We liked it so much I bought another one for my parents for their RV.
Answer: Hi. This heater has the standard 2-prong polarized plug. It doesn't have the 3rd grounding plug. So from what you are saying, this wouldn't be the right fit for you; although it's an excellent heater. Hope this helps! :) Have a wonderful day!
