Definitely worth it for what it is
I installed this in my 1998 Chevy. S ten, it's only been in there for about a week.But for sixty two dollars.So far so good I had no heat in my pick up.And this works pretty well for what it is in a single cab. Pick up. It's definitely better than no heat. Especially for the price the noise level, it's fine, especially if you have no heat ☆☆☆Also does come with the plastic hose☆☆☆

very cheaply made
Arrived promptly that's the positive. The switch is defective. If you wiggle the switch wires it will run, but not too long. The hose clamps they send with are garbage, they strip out as soon as you apply pressure securing them. The air hoses that are sent with are completely useless. I'm going to replace the switch on my own as I have the heater plumbed in with modified heater hoses. hopefully the fan motor doesn't burn out

Good for the price
Good built unit, easy to install on Polaris ranger 900xp under dash, the pipe fittings could be made better, and fan blower is a little weak, for the price really a good heater

Great heater, subpar clamps
The only thing preventing a 5 star review is the crappy clamps. The parts and heater works amazing. The clams are junk and split when you tighten them down.

passable
fonctionne relativement bien malgrée tout mais la puissance du ventilateur est riddicule je ne recommande pas pour ce point la mais fait un peu de chaleur donc c'est mieux que rien

Worked exceptionally well
If you are even a little handy you should have no issue, I had to by a 1” to 5/8” fitting instead of the supplied fittings. Everything worked excellent it was -10 to -15 the last four days and I find once the bike reaches 180°F it well finally start to blow hot air!
