I've had many "bottom end" Lasko's over the years. All basically the same.. rectangular steel box, 2 braces holding the motor (one end only) and a 5 bladed fan. The box owes its rigidity to the two plastic screen grids screwed to the front and back. All seem to have plastic "feet" to help stabilize it front-to-back so it stands better from the force of air being forced through. They typically are all 3 speed.

Lasko's are mass produced, American-made fans retailed widely at many outlets, at least in the USA.. usually larger chains.. during warm seasons. They normally retail for $15-20 and represent excellent value at that price. If you order by mail and have to pay shipping, much value is lost. (this particular offering sells 3 units so the shipping is shared to bring the per-fan cost to around $25 each.. assuming of course you can use 3 fans)

Over the years, I'd say they average 3-6 years or more of regular use (many thousands of hours) Their mode of failure is usually shaft support failure.... they just get so they won't "go" when powered on. Of the many brand names I see on these box fans, I believe the Lasko is the BEST quality and longest serving.. they are designed and made in the USA.

Good points
*they are cheaper than virtually any other option (except a few other similar clones.. they all are basically identical.. they often are offered as "promo" or "loss leaders" at the "big box stores" for under $20 each)
*barring physical damage they work quite well for many years.
*they CAN move a lot of welcome cooling air!!
*the most reliable of the box-fan suppliers in my experience

Minor "problems" ..
*BIT loud on HIGH (not unreasonably so.. when you move this much air, it makes noise.. the fan itself is quiet)
*plastic blades snaps rather abruptly if a child or whatever sticks something into the blades while its on (at least I've had this happen once.. not sure if all blades are that brittle.. I snapped blades from another unit onto it and it served a long life)
*the design is not "efficient" if you need truly forced air pressure due to lots of "leakage" front to back around hte blades.. Lasko makes a shrouded fan at a higher price which would be much better in that application&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Lasko-20-Weather-shield-W-Thermo/dp/B000RMFIM6/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Lasko 20" Weather-shield W Thermo</a>
* The narrow width make them VERY prone to falling over (even with the plastic "feet" attached).. I don't think I have had a one that hasn't fallen over several times.. luckily they are rarely damaged by this. You should just plan on putting it where you can "lean" one edge of it's intake side against something

I see no mention of power consumption in the product specs, but they seem to use about 90 watts (all of them have power usage tags on them. but you'd have to have the unit to look at it) At average USA power cost (9-15 cents/kwhr) they are cheap to operate.

All in all I RECOMMEND THE UNIT if you can get it for the $15-20 range (watch for sales or "loss leader" values too).

It is worth noting that the above "weather-shield" thermo-controlled unit (which is a considerably better fan in construction, water resistance, and air movement).. the thermo control may be a plus to you, but I just turn it off or on as needed) is a "good value" especially if you're having it shipped as it is only a couple of dollars more than this one (as shipped) and includes free super-saver shipping IF YOU NEED it shipped!

If you plan to use it in areas or where it will be exposed to some water now and then, you probably should go for the above-mentioned "weather shroud" unit&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Lasko-20-Weather-shield-W-Thermo/dp/B000RMFIM6/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Lasko 20" Weather-shield W Thermo</a>... made to sit in a window and survive the occasional rain storm. In that case the thermo control could be more valuable for unattended operation.
