Having had this for a while now, I can say this product works exceptionally well. I have just spent the last couple of days re-jigging my hi-fi and AV setup, and I was able to switch from the AV receiver through this without issue.

This is something that the receiver refused to play ball with other switches.

hdmi switching the easy way
23 Oct 2025
Verified Buyer
I took this out of the box, quickly read the instructions and fitted it into my system. Worked first time and continues to work faultlessly.

Don't be tempted by £25/35 boxes, this just works.

Excellent and excellent service into the bargain. What's not to like.

The go-to mfr for reliable A/V kit.

Verified Buyer
This HDMI switch just works, unlike many consumer-grade units.

They are, like all Blustream kits, bullet-proof. It's a basic but my go-to, ultra-reliable HDMI switch.

Good little unit
8 Sep 2018
Verified Buyer
Good little unit. Happy with the purchase of this little unit. Decent quality for a good price. One input is running a signal sent through an extender that a different switch was having difficulty keeping stable.

So far, no issues with this switch and I’ve run a lot of different sources and devices at it. No hdmi handshake issue either which can happen with semi-pro kit.

Easy to order and fast delivery. Happy with the purchase
