ANYONE HAD BAD EXPERIENCES WITH THEM?
I just took mine away for its first trip, went did some beach runs where I had to drop the pressure down to 16psi.
On getting back onto solid gravel roads, pumped them back up to 36psi and the solder joints on the Negative lead fell off the clamp, and the positive lead off the on/off switch fell off.
AFTER CHECKING.......ALL THE SOLDER JOINTS ON THE UNIT ARE DRY AS.
So much for QA but I suppose thats why you pay $70.00

Paul I have not heard any other complaints. Considering that you could have paid $249.00 for a basically identical unit from Bushranger, would that have made you happier? It really sounds like you may not have had a good connection and consequently increased the current causing heat, or of course, you could have got a Friday afternoon one just before knockoff.

A bad connection decreases current Ozi. Reason bad connection gets hot is it has resistance, current flowing through resistance produces heat. P = I(sq)XR p=power=heat, I=current and r=resistance.

All true, but I'm just glad it happend when it did........after the tyres were inflated.
The stupid thing was I sat around for an hour thinking the darn thing had got too hot and the thermal cutout had kicked in........ I then decided it was time to get out the screwdriver.
Now that I am back
home....time for the soldering iron and some icy cold beers !!!

Apart from those problems how did the compressor go. What size tyre were you pumping up and how long did to take? Was very close to buying one a week ago.

Didn't time it to the minute but it was in the range of 15 minutes from 16psi to 36psi, To do all 4 tyres.
They were Cooper 265 R16/HT.
It was enough time for the kids to run off and play in the playground

AND Finally,
When you connect the compressor hose to the tyre, you get a reading on the pressure meter, you turn the compressor on and you get a different reading.
I've learnt that when the compressor is on and the meter reads 32psi there is 36psi in the tyre.

Paul,
My Grunter has a battery cable that needs to be at least a metre longer.
The pressure guage is also a dicky one. Have to guess the pressure and check with my reliable guage.
I would have exchanged it for another but lost my receipt and also had the thing for a month before I used it.
I will lengthen the cable and maybe fit a better guage.
Other than that it worked fine. Mind you, I've only used it once so far.
Regards Tommyruff

Hi Paul,
We recently bought the Repco version of the Grunter...without checking I think they call it the Cyclone. Anyway, same unit just has a long hose and a bag.
Only used it once so far but performed admirably. Actually, our travelling companions had an ARB a/comp. and we had our tyres re-inflated before them.
Details were 6 tyres (4 on car, 2 on campertrailer), all Coopers A/T Discoverers 265/75. Inflated from 18lb to 35lb, took about 3-4 minutes per tyre with no noticable drop in performance from the first tyre to the last.
If your compressor isn't performing to this level, you may have got a bad one. Take it back and ask for an exchange.
