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☆☆☆

Nice Universal Heater, Easy to connect
One of my food truck is one of the older truck that the heater just doesn't work anymore and I bought this to replace it. PROS: -- Nice unit -- Small and it fits right on the dashboard or in the front of the truck -- Pretty powerful fan -- Warm -- If you don't use any of the duct hose, it's blowing pretty powerful. CONS: -- The duct hose was poorly made. Put them on and the came off easily. Ended up getting the aluminum duct hose for them. -- Once connected, the fan doesn't appear to have enough power to push the hot air through those four hoses. -- Need to be very creative on how and where to install it or you are going have one ugly spider look-alike heater on your dashboard. OVERALL: I bought this heater mainly to keep the windshield warm during snow or raining season so it doesn't fog out. It seems to do the job. I wish the fan is a little bit more powerful so I can at least warm my feet, hands, while keeping the windshield clear of snow build-up, etc.

Would recommend buying something nicer
Heater works ok pushed out lots of air until you hook the duct to it. If you mounted it in the cab and don’t use the ducting I think it would work better but with my Honda pioneer 500 that’s not the case

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!

It looks to be a good product. Easy to install. The only problem was that the switch didn’t work properly. I had to pick up one at a local parts store. Installed it and it was fine.

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
