Found at kmart Window Thermometer

[Sublime]

I have used them and found them lacking both in acuracy and reading the temp, and they use sticky tape. I like the suction cup (thumbs)

Oh ok, yeah mine is probably inaccurate because I only paid like 8 bucks. Beats trying to just eyeball the environment though haha. Yeah the sticky tape is a downside... It's all good though, whatever you find works best.
