Excellent Service and Support

Very good service

Technical support was helpful

The product arrived as per the time notified, packed in a very good way with plenty of protection for the electronics. technical assistance was fantastic in helping with the set-up of the system and the website ordering was very simple. In simple terms fantastic service and would not hesitate to use them again

Truly excellent customer service… We bought a GSM intercom about 7 years ago and it’s been pretty much bulletproof until today (or so I thought!) It had stopped dialling when the button was pressed, wouldn’t respond to any SMS commands and there was a quiet buzz coming from the speaker. I feared the worst. After cycling the power off and on in time-honoured IT department fashion, and after removing and reinserting the SIM, I called ControlFreq expecting bad news, “sorry we can’t help you”, “you’ll need to upgrade” or some other expensive variant of reply. Steve spent some time on the phone with me, advising and trying to diagnose the issue but when there were no signs of life from the internal LEDs, the system was pronounced dead. Steve then suggested that maybe there wasn’t power getting to the system which I was pretty skeptical about because how else would it have the power to make a buzzing noise, right? However, swapping the 12v supply that’s been doing the job perfectly well for 7 years sorted the issue immediately and our system is working perfectly again. How many other places can you go for this kind of help and advice on a product that was bought 7 years ago and has probablyj been superseded several times over? That’s truly excellent customer service! Thanks

Great service and advice as usual, thanks!

Great customer service and back up. Equipment works without fault, talked through step by step commissioning sequence. Highly recommended

Works well

Always get excellent service from this awesome company. Great technical assistance Thank you as always

I've used th G1-3G and G1-3GW 3G remote opens and they are great products with good technical support. The administration plans for their GSM openers are a little pricey if you need to alter authorised users a lot but you can do this by text message for free. I've tried a few mobile phone remote relays and these are by far the most polished product with a great set of features and ease of use.

great products and service

Very happy with the advice, great to be able to speak to someone who understands the requirement.

ControlFreq is one of my favourite suppliers. Technical staff always availble for tips and advise. Never had any issue with any products or orders.
