Reply to BeeCee comment : very funny! "small purchases ... should go to local hardware store" -- Oh yah ! Local hardware stores do not sell electronic parts ... It is almost impossible to find any such local retailer of electronic parts anymore, and the photo from their store looks like a retailer.

I've found these guys to be accommodating, friendly, and professional. I think they are geared towards industry folk. So people walking in looking for an adapter or a little one off consumer type thing may be put off. They only service business accounts now.
They offer quality product that you won't find at say, Lee's Electronic (nothing against Lee's, love those guys, bit they are more consumer based, not pro based) if you are looking for pro level product for meeting specific industrial ratings, this is the place to go. RP was ok but unfortunately they dropped the ball a couple of times when

Clean and light shopping floor. AC provided during hot days. The employees are very nice, friendly, and helpful. Price is acceptable. Serve speed and check out speed are fast. Credit cards accepted. No public restroom available, however you can request and it will be based on individual case. Free parking lot available.

Uummm... Quite a number of negative reviews here. That many people can't be wrong. I was here yesterday and was treated very badly. Blank stare in the tall man's face. All I'm looking for is a plug! If you don't want public walk ins and only look for wholesale business then put a sign on the door... We don't want your money public people.

I buy my supplies here, great selection and service.
poor reviews are generally from people with very small purchases that should be shopping at retail hardware stores instead of wholesale distributors

Like others have said, the crew here are totally disinterested. The few times I've been desperate enough to go there I braced myself for a blood pressure increase. They are liable to look products up on google if you have a question, as if they knew zero about the products they offer. It's like going to a nursery and asking for petunias and getting a blank look.

I have used this business for work purchases several times and have had good experiences with them. I have also purchased various automotive and other DC current switches for personal use. MRO is Radio Shack on steroids and then some. They carry a HUGE assortment of switches, connectors, LED's, they make custom electrical cables, they carry electronic service tools and soooo much more. If you need something electrical, they will have it or can get it for you!

In a nutshell know what your looking for before you go in. Staff isn't that knowledgeable and for the most part will look at you with a glazed look if you ask a question. Example:
MRO:We don't have bridge rectifiers
Me: Ok where are the diodes then I will make one from discrete components.
MRO: Over there sir.
Me:You know you have a whole shelf here of bridge rectifiers right???
MRO: Where?
Me:The one labeled bridge rectifiers across the front of the shelf.

Oh Please save me! 12.00 for a 12 volt cig adapter when I could get the same thing from a shop over on renfrew for 5 bucks? I just wanted something to plug into the company car so I could have a 12 volt lantern in case I brake down on the road and this smuck tries selling me the most expensive thing they got in the shop. When I asked about the other lighter adapters, he told me they were junk. So if they're junk, why are they selling them? Then I had a friend that went in there to by a simple Anode Diode for a circuit he was building and the guy got the part number wrong and ended up making up

Service was horrible. Walked around the store for 10 minutes and not one person came to help me. When I went to the desk for help, the guy was rude and unhelpful. Must of been the same guy that the other reviewed described. When I showed him the part I was looking for, he pointed to a shelf and said "you can look through there and see if we have it". I have never experienced such poor customer service. Would not recommend stepping foot in this store.
