Excellent customer service. I bought a Stryker SR-955HP tuned and peaked. Radio sounds nice!!! Thanks!!! 🚛🏴‍☠️

They are the best. Great service. Wonderful hospitality.

Great shop and owners, lots of inventory, had an antenna installed very precise and high quality workmanship. The Boss lady is very knowledgeable, thanks.

She hooked up my radio in a new pickup to me, got the antenna hooked up and tuned. Great work and a super nice gal. Thank you. This was a few weeks ago. Works great!!!

Great service with excellent friendly people who are very willing to help in anyway they can. (sorry for leaving my drink)

The lady that runs Circuit Master really knows her stuff. And my husband said she is easy on the eyes. I recommend this place for any kind of CB radio issue.

Excellent shop! Had a CB antenna mount break inside my mirror housing. Pulled up to the shop and the tech came out and fixed it in less than an hour. Replaced corroded bits and radio system is good as new! Very reasonable cost/price for this quick service!!

The gal that owns the place has been there over 25 years and knows her stuff. Will go out to your truck to diagnose issue with coax and antennas.

Do good work good prices

This lady knows what shes doin. Not like the other shops Ive been to. If youre looking to get your rig done rite, this is the place to go.

Phoebe was extremely kind she was able to Peak and tune my CB radio for only $35 big difference next time I come to Iowa I will probably buy a new set of antennas and a microphone

Very helpful and knowledgeable, also willing to talk shop. Ill be stopping in here again

The owners were very helpful in getting me what I wanted

Great customer service, expertise, and friendly. One of the best repair shops around. Would recommend to truckers, Cb enthusiasts, and ham radio community. Good variety of new and used equipment. Thanks Circuit Master.Bob of Waterloo

1st time there & my impression was that it was a cool little place ! They had anything that has to do with CB radio including some vintage radios that any radio buff would like to have ! So if youre interested in CB radio and accessories this is the place for you

Very help full ow things

Very knowledgeable with CBs and accessories. Friendly staff willing to help.

Great customer service! Polite And prompt. I thought my CB was headed for the trash can. $35 tune and I was back on the road!

First and foremost talking with young man was refreshing. A second generation “Circuit Master” who really seems to know a helluva lot. He’s extremely knowledgeable. Secondly, he stayed after to work on my install well into the evening on a Saturday when closing time is 2pm. Clean and proper install, no exposed wires. Very FAIR prices. I will be back to do my CB work. They have earned my business.

Great place for CB work, fast and know their stuff.

The Best Shop an Town

Very poor customer service. Dropped a cb off months ago to get some work done on it and every time I called to see how they were coming on it they always said they needed more time. Now they wont answer their phone or return calls.

Very nice people, Was very helpful with tuning antenna and new end on coax. I didnt have a radio tuned there so cant give any info on that

A small shop with a big heart! Super service! Committed to detail and not hesitant to take time with each customer.

Great shop and guy. Tuned up my Cobra 29 in no time. Also replaced a coax connector for me. Very reasonable pricing. Once the radio was done and I hooked everything up. I found an issue. He came out to my truck and discovered a split in my coax line requiring another connector. He took care of that and cut the whip to tune my Wilson 2000. Great guy carrying on a family owned shop. Thanks again!!

What a joke. Their website says open until 8pm. Google says open until 8pm. Start calling at 530pm and keep repeatedly trying. No answer to any calls. No recording stating hours or even a voicemail. Called the truck stop and get told they probably left at 5. What a way to run a business.

They get them fixed fast

This place is great!!! I just had warranty work done on my 3300 and there quick and know what their doing. Thank you!!

This CB shop is quick and inexpensive. They have been around for many many years and know what they are doing. The owners are always there and even when they are not the boy running the place is their son so it is not some young punk working on your radio. When you are at Flying J or passing by it is worth your while to stop in and make sure your CB set up is right.

I’m trying to find out if this business actually exists?I sent my Galaxy radio to them in May for some warranty work. I was told it would be approximately 5 weeks for repairs. And after 3 months now have yet to get a return phone call after several attempts to reach them. Galaxy has even made 2 attempts to reach them to get my radio sent to California. They also have had no luck ether. Getting my radio back or reaching them on the phone. So unless you have unlimited time to sit and wait or don’t really need your radio for a long time. Keep Truckin!

Knowledgeable...best in the business...affordable, friendly, stand behind their work. They have made all of my radios...base and mobiles better than factory. Other shops should look at Circuit Master as a model of how not only a CB shop but any small business should be operated. I will not allow anyone else nationwide to even look at my electronics.

Very helpful.

Very helpful. Got my radio worked on and my antenna issue resolved quickly. Im guessing fairly priced since this is the first ever cb shops Ive been to. Ill definitely be back if I need more help.

5.99 for a coax connector, OK great how much to put it on?Nothing if you bring it in, Its $25 for me to walk outside.First, to say if you bring it in. is the stupidest thing I even heard. It is a piece of coax installed in the truck. Otherwise I would just replace the coax.Second, if you think Im paying $25 for you to get off your lazy ass, your out of your mind. And yes I can do it myself, its not rocket science moron!

He worked on my General hp 40. No problem. Works better then it did. Great job . Knows exactly what hes doing.

Good place good work and good people no complaints did everything I asked and then some

I had a rci 63ffd4 that I had busted the RF knob off and taken it to two other places to get fixed. One said I had to send it back to ranger, the other said they didn’t have the part. Circuit master had the part and had my radio fixed within 15 minutes. They are extremely nice and professional. I would highly recommend this cb shop to anyone.

Good job !! Called about 90 mins out was told to come in. They worked on my radio added some power, installed a new bracket, coax and antenna on my 2018 cascade, everything working great. Thanks guys Ill be back😁

They are very friendly and trustworthy. Only place we go to for our CB accessories and repairs.

Wonderful shop. Matt (young guy) is surprisingly knowledgeable and incredibly helpful. This is the only shop I will buy radios from.

Went above and beyond with service. If I need more help will be stopping by

Zack, (Circuit Master) repaired by General Lee C/B, since the Talk Back (Echo/Reverb) died ☹️ & Replaced the switches on my Road King RK56P & Astatic 636L 🎙 Microphone.Under $50.00 Total👍My General Lee C/B sounds much louder, & clearer on the Cobra 🐍 External 🔊 Speaker, now😁Throughly Satisfied Customer 😎

Great customer service

Had a great experience at this CB shop, He repaired my general Lee ...Set me up with the right antenna and Mount Got me all wired up and going after closing time .Thank you circuit masters for the great work and great customer service

Every CB shop opens and closes at really stupid hours! Really you want to make money but close at peak hours when truck are parking for the night! Doesnt seem like they know how to run a business to me!

You can find the same cbs on amazon a 100$ cheaper

Very friendly, excellent experience. work the extra hour. awesome.

Looks like the radios are way over priced. I spent over $100 less on the Stryker 447 a few hundred miles down the road

Awsome shop very respectful and does an awsome job....my dad went to circuit master when he ran the road and circuit master is the first cb shop i been to and only shop that i will go to thanks for all the help and amazing n fast service

Dropped my broken cb off on way to east coast & picked it up on the way back. My cb is fixed & is better than ever. Connex 3400hp

Excellent place good people very informative. They dont just do it and then charge you high amounts of money. They talk to you about it first and let you decide. But they did an awesome job at an awesome price on both my galaxy dx 48 T (200+ watts) and my dx 959 (25+watts)both had multiple issues and now both are loud and proud. Very honest and professional. I wont go anywhere else

Very nice people and very reasonable prices

Great place

Guarantee we wont be back, $65 for a loose wire haha... Should have listened to all our trucking friends and not even stopped here!! If I could rate 0 stars I would!! If ya want ass raped without lube stop here!! $15.90 just to look at it, when most people will look at them for free!

Nice people good prices

Decent prices and good service.

Never heard back from them after sending in my radio. Hope they are ready to go to jail for mail fraud.
