I recommend this because smd items are hand made and hand tested and work great for those tedious tasks were you are trying to tune your sub to your box and also is a great learning tool on how to mess with car audio.
I do not own 1 but I have seen how it works and I recommend this item only because of how it works .
Only thing I don't like about this product is the price but I understand that it was hand made not mass produced.
Tools like this are just "Staples" that are needed in order to perform a "quality" install for your own personal use, or for customer installs. A tool like this is a time saver, and a valuable tool to have in the tool box. SMD products are amazing
Great product so many features looking forward to have all smd's stuff
Nice desing and easy to use
I just received this toy and it's ok. A bit expensive maybe, and I had to pay custom clearance to get it here in Spain, but that's not their fault, of course.
I had used long time ago the IM from RockfordFosgate and the signal level was quite lower, almost inaudible. I think SMD is better as a Signal Generator than RFosgate's. Also the display and overall manufacturing is much better.
I would prefer though that the frecuenciy adjust were continuous and not to have to select RANGE in order to cover all the bandwith, but I guess it's a minor defect.
I can not rate durability, but it seems well built
