Solid signal generator, delivery okay

I purchased the FNIRSI signal generator for my home lab. The device itself is quite good for the price point, offering a decent range of functions and a user-friendly interface. It performs as expected for my needs, which is mainly testing audio circuits. The packaging was adequate, and the item arrived without damage. My only minor critique would be the delivery time; it took just under two weeks to arrive in New York, which felt a bit slow compared to other online electronics retailers. While I'm generally satisfied with the product's quality and value, a faster shipping option would definitely improve the overall experience. Customer service was not needed, so I can't comment on that aspect.

Oscilloscope and leads, good kit

I ordered the FNIRSI 1013D handheld digital oscilloscope and an extra set of oscilloscope probes from their site. The ordering process was straightforward, I found what I needed quickly. Shipping took about 8 days to get to me in California, which was a bit longer than I hoped, but it arrived well-packaged. The oscilloscope itself feels solid, and the screen is quite clear for a portable unit. I had a quick question about calibrating it, and their online chat support was responsive, though it took a few minutes to connect with someone. The probes are decent quality, no issues there. It's a good tool for hobbyist electronics work, just manage expectations on delivery times.

Affordable USB tester

I needed a USB tester and saw they had one for a good price. I always look for a bargain. The sitewide sale got me a little extra off, which was great. It works as it should, nothing fancy but gets the job done for checking voltage and current. Shipping was free, which helped the budget. Felt like a good deal overall, definitely worth what I paid. Only minor thing, the screen is a bit small but readable.

Good value, minor shipping delay

I purchased the FNIRSI 1013D handheld digital oscilloscope. Overall, I'm satisfied; it's a very capable device for the money and has helped a lot with my hobby electronics. The ordering process was straightforward. Shipping was a bit slow; it took around 10 days to arrive, which was longer than I hoped. Customer service was responsive when I inquired about the delay, though. The oscilloscope itself performs well, but the instruction manual could be a bit clearer for beginners.

Awesome power supply!

I bought the FNIRSI DC power supply and it's fantastic! I've been wanting one for ages and this one really delivers. It's super easy to use right out of the box and feels really well built. The display is bright and clear, and I've already used it for several small circuits. It's exactly what I needed for my electronics bench. Definitely going to buy from them again when I need more gear. Highly recommend this brand to anyone into electronics!

Got my new multimeter!

I ordered a digital multimeter last week. It got here pretty fast, took about 5 days to reach me in California. Packaging was good. It works as expected for my basic home projects, no complaints there. Just wish it came with batteries.

Always reliable test gear

I've bought from Fnirsi before, this time it was a USB tester. Like my previous orders, it shipped quickly and the product was exactly as described. Their gear is consistently solid for the price. I keep coming back because I know what I'm getting. Only once did a shipment take an extra day, but that's minor.

Good for the price

Got a digital multimeter from them, the one that also does transistor testing. It's pretty neat. I needed something for my little projects and this one works fine. Shipping was okay, didn't take forever but wasn't super fast either. Overall, I'm happy with it, seems like a good deal for what I paid. Just wish the instructions were a little clearer sometimes.
