These guys don't know what they're doing they give you stuff that they think is going to work for a car and doesn't they lie to you and waste your time

I bought a rebuilt alternator from M & M Alternators for only 55 bucks and it came with a 2 year warranty! The customer service is great and the prices are low. Stop over paying for car parts and check them out today!

Bought a used battery from here for 30 dollars. can't go wrong working with these guys, the prices are low and the quality and customer service are high. thanks!

Got a new battery for my car for 50 bucks. It was amazing. I'm super happy with it. Thanks again!

las peores partes que me han instalado servicio pésimo Solo mikey mouse hacen caste el doble por lo que hicieron no recomiendo este lugar para nada mi peor enemigo

Did the bate and switch on the price almost double the price!!!!

Great Battery for my brother Tom, My brother bought a battery for his Truck that i was usuing for work a the Battery works great ! plan on usuing them for wheel chair batteries.

I bought a battery from these guys on March 5th for my VW Passat and it went completely dead in 20 days! I was so mad when this happened and when i called them about it I was told that would happen if I didn't run or use the car but yet I was using every day since I bought the darn thing. The nerve of that smartass! Every other expensive mechanic I called told me that if the battery died out in less than 30days then these people sold me the wrong battery for my vehicle or they just never fully charged it! Everyone look out for deception and make sure what your paying for is the actual product/item you need and will work for more than 30days because its a hassle to go back and forth so much and can get irritating.

Reliable batteries and great fast service!

low cost batteries and reliable ....thats all got to say

i would like to say this is one of the best alternator places i been too thats not expensive like the autozone n napa ..had my alternator rebuild for $50 with a 2 year warranty when autozone offer it at $139.99 and 1 warranty ..thanks guys

definetly never coming back EVER!!!!! got my RV alternator rebuilt here it lasted less than a month WTF!! for trying to save money it costed me a lot more!!! i had to take it to the dealer. next time I'm going to pay attention to the reviews instead of risking it!!! the cheapest cost more.

this place really sucks bad service,bad quality and they dont give the warranty they say ,have my alternator rebuild twice they told me it was an electrical problem took it to another place in Fontana got it fix IT WAS THE ALTERNATOR , I would NOT recomend this place EVER!!!!.

*ASEMASTER TECH you mention that you waste 30 mins creating a account( ON AUTOMD.COM) for the website to post a review but you had plenty of time to post a similar review for about 5 different website all this sounds like a personal or business competion review. ( http://www.automd.com/shops/m-m-generator-alternator_260349/)



*Our batteries are Semi-New and no we do not clean and put them on the shelf we have our company that supplies us with the batteries new/semi-new



* Our work is guarantee for 2 years (batteries 6 months ) . When your local Auto Parts store don't have what you need guess who they call.



Any customer that feels that was treated bad please let us know and we will take care of the problem

Called for starter they said they had it on stock ,I get their and they said they would rebuild it . I waited 3 hours came back still not done . They have been in business cause once they have your part you are at their mercy. Anyone can get a customer when you advertise but they will not get a return visit. These people are crooks they are not going to get my business again . Now I'm still at their mercy going on 4 hours can't get my starter back or my money.

I bought a starter from them a few days ago, it caught fire!!! So I go back and they said Oh its your car, then they said it was my install error. Theres 2 wires and they cant be switched because one is a 16G and the other a 4G! So they told me they would replace it once, I put it back on my car, and it started to smoke after cranking it twice! I Went to autozone, bought a cheap reman one, and it fit and worked PERFECT! Screw you guys!
