121 customers mention113 positive8 negative

Customers find the bleeder easy to use. They mention it has great suction, is easy to setup, and can pull either fast or slow. They appreciate the trigger's ease of use and the conveyance of the brake fluid. They also say there is little to no mess when using the bleder, and cleanup is a breeze due to its large container. Customers also say the vacuum system is cleaner, easier, and faster than the positive pressure system.

"...This thing pulls a pretty awesome vacuum at 120 psi, but obviously your compressor will have a harder time keeping up, as mine barely did...." Read more

"...It is easy to use and only somewhat aggravating to drain at best. I found it an easy process...." Read more

"...It's incredibly straightforward to use...." Read more

"Absolutely Amazing Tool.Gets the job done so quickly and Easy to use.Rate it a 100% Useful Tool." Read more

70 customers mention59 positive11 negative

Customers like the value of the hardware tubing. They say it's well worth the price, easy to use, and provides quality for the price. Some customers also mention that it pays for itself really quickly.

"...This is a great buy and great tool." Read more

"...Hooked this up and was done in 30min. Definitely worth the money spent." Read more

"...Well worth the money, so if you're questioning the price, rest assure that it's worth the $100.00 bucks. Easily one of my favorite tools in my shop...." Read more

"...can order a 6’ hose for this from the manufacturer and the price overall is reasonable. I remember paying $160 for my last one in the mid-90s!" Read more

38 customers mention16 positive22 negative

Customers have mixed opinions about the suction of the hardware tubing. Some mention that it has amazing suction, enough to empty the reservoir and pull fluid through the lines. However, others say that it would not produce enough suction to pull brake fluid out of the line, drawing in lots of air and very little brake fluid.

"...it started spitting and sputtering from the exhaust and the vacuum stopped. I had to let it sit for a few minutes and then tried it again...." Read more

"...I do like that you can use this for general vacuum suction but again, that's not something worth $100 when a $3 syringe will work...." Read more

"...This causes the suction line to pull air, so it is very difficult to tell if air is in the line." Read more

"...The suction is plenty to empty the reservoir and also pull fluid thru the lines...." Read more

29 customers mention11 positive18 negative

Customers are mixed about the fit of the hardware tubing. Some mention that it fits well in the car, and is compact in size. The bleeding nipple is flexible and fits snuggly over the port. However, other customers say that the parts are cheaply made and do not fit well, and that it does not include fitting for smaller bleed nipsles.

"...Missing were the hose, couplings and adapters required to hook it up to the air bleeder unit...." Read more

"...The nipple on the vacuum end fit very securely and would stay on with out me needing to hold it in place...." Read more

"...The plastic parts are cheaply made and do not fit well but seems to work ok." Read more

"...It's clearly not one size fits all." Read more

27 customers mention10 positive17 negative

Customers are mixed about the fluid drain. Some mention that it sucks out fluid at an ideal rate, while others say that it pulls the fluid a lot slower than expected.

"...Overall, it's just okay. Pricey and honestly not that much time was saved because I had to doublecheck my bleeding to make sure all the air got out...." Read more

"...Draining used fluid is suer easy by removing the anodized aluminum cap in the top (catch basin does not separate from vacuum handle)...." Read more

"...This does mean that it performs a little slowly due to the low PSI...." Read more

"...After it’s first initial use was good, after that performance goes down...." Read more

41 customers mention7 positive34 negative

Customers are dissatisfied with the air resistance of the tubing. They say it tends to pull air in around the bleed screw threads. They also say the air comes into the brake line after using it. Customers recommend adding Teflon tape to the threads to prevent air from getting in.

"...This causes the suction line to pull air, so it is very difficult to tell if air is in the line." Read more

"...My only issue was that it consumes a lot of air, and I had to recharge my 3 gallon compressor several times to finish all 4 wheels...." Read more

"...I found it impossible to not pull in some air at the hose attachment to the bleeders...." Read more

"...I would give the unit five stars except for the issue with the air. Would I recommend? Sure. It still worked...." Read more

Instructions were included
A few reviews stated they didn't get instructions. My DID include them. I posted a picture for those who didn't get them. I haven't used it yet and have never had one before. It seems to be very solid construction and feels sturdy. I cannot wait to try it!4/5 for delayed shipping.Update:I have used it and it works great!It has a recommended psi to run it. I ran it at 100 psi at first. I recommend running it at a lower psi because at a higher pressure, it let's air seep around the bleeder screw into the line as if you have air in your brakes still. After turning it down to 80 psi, I had no more air bubbles in the actual tool hose.
