Happy with my purchase.

Its larger than I expected, I didnt look at size and weight when made the purchase. It works as good as I hoped. Airs up fast. Gauge isnt accurate when pump is on but you figure it out, about 10psi more. I get it there then check with a seperate gauge later, usually adjust down 3 lbs or so. It gets hot, I noticed when trying to disconnect hose to store back in bag, guess its expected, seems to cool off quick enough. I will be keeping a set of gloves handy. I bought a seperate carry bag from harbor freight, a bit larger and sturdier. Used the bag it came with for straps and shovel. I dont see getting better than this for the price.

Excellent compressor & kit

I was looking for a compressor & had a budget I was trying to stick to, but nwas not finding any I felt would be of the quality & performance I was looking for. I found this on on sale here & it was just over my budget, but the performance, brand & kit contents were what I was looking for. So I bought it. All I can say is wow. It works excellent & I am now the envy of my group when we are airing back up after a 4X4 session. This compressor is quiet, fast, powerful, looks great & has all the items you need. If you are looking for a portable compressor, you can't go wrong with this compact powerhouse.

Smittybilt 5.65.Air Compressor

Worked great! Was surprised at how fast it aired 4 285/70/17's from 12 to 30lbs.

Best bang for the buck!

I researched and researched these portable compressors. Found myself coming back to this Smittybilt again and again. The CFM rating, PSI rating, etc. all top notch when comparing to other compressors. The best part, it has one of the highest CFM, PSI, ratings but when comparing to like models from other manufacturers, this one was less than half the cost. I understand that it is not a 100% duty cycle unit, but for what I need it for (filling up four 36 IROKS when jumping back on the pavement) this unit performs flawlessly. Highly reccomend this unit.

Definitely worth your money!

I was pleasantly surprised at how well this unit performed. Not only did it air up all four 33"x 12.50" tires on my Jeep, but it also aired up my friend's Jeep with 33's and another with stock tires. We even aired up a Toyota PU with only 5 lbs of psi up to 35 lbs psi! FOUR vehicles in under 45 minutes! To me that's value. The unit did get hot at this point. I highly recommend this unit to everyone that goes off road and needs to air down. Airing your tires back up will be a simple breeze for your own rig and your buddy's as well.

Great Compressor

Worked great on my recent Colorado trip. Filled my 32's in no time flat. Marked down because it gets hot and has to cool before putting back in carry bag and because the gauge wasn't quite accurate.

Works great and is a great value

Just bought this on the reccommendation of Mike at the Fresno store instead of one of those power tanks. (Didn't like having to fill them up every other time) He says he has been using it for the last year on all his vehicles. Gonna use it this weekend at Ducy Ershim. Did a trial run at home in my garage and it worked fantastic. Took my 35's from 10 to 30 psi in under 2 minutes. Great carrying bag that is heavy and compact, which for a jeep is a must!!!!!
