A good temp range is 365-385 F, but you can't count on an accurate display with the cheap vapes. You should find the vapor range by where you get vapor and the color of your remainss. Start low-where you first start to get some vapor. The high end will be where you get harsh vapor and your remains are black. Your operating range will be between the two extremes. Your remains should be a medium brown. You can increase temp to the harsher vapor range (leftovers dark brown) if you like, but the vapor isn't as clean at higher temps.

At the right temp you should get a few tasty hits. Stirring the bowl and continuing to hit it will finish off the bowl but the final hits won't have the good taste of the first few. That's just the way it is. You're hitting some herb that's already been vaped.

Prop up the back end of the vape to get a better angle. Adjust for a horizontal position. You can also turn it upside down or on its side.

You may not get a good vaping range or consistent results out of a cheapie like this, but hopefully you'll get good enough nice vapor hits to make the case for a better vape.
