I thought it was important to submit a review for this product as I really struggled to find a baby monitor on the basis of the current reviews on the site. It seems that any baby monitor on sale has both 5 star and 1 star reviews, so it is really hard to actually make a decision.
I chose this product because it was actually recommended by a different retailer, and I thought it was worth taking a gamble because it is a good price. It is also small (rather than these ridiculously large base units that seem to be dominating the market) and it is simple - all you really need is a unit that relays the sound of a crying baby isn't it?
We live in a rural building with slightly odd electrics, and have always had buzzy monitors in the past. This is clear as a bell which is great. I haven't anything to say about the build quality, nothing is irritating about the product.
It is worth mentioning that the monitor only cuts in if it 'hears' a sound and then that sound is maintained, so I thought it wasn't working at first. This means that you can't hear your baby breathing if that's important to you (it was for our first baby, but a bit more confident with number 2 so not necessary!). The unit also appears to have a slightly smaller range than our very old Tomy unit, but I'm talking about range outside of the house.
I would certainly recommend this product.
