Rechargeable Guitar Wireless System Transmitter Receiver with 50m(164ft) Transmission Distance 100 Channels for Electric Guitar Bass and Other Instruments

I have owned this wireless setup for 1 week now. So far, they perform very well. There is not a noticeable loss at either end. If you are in the studio... use a good cord. This will work for most applications. The battery life is plenty. I don’t often play for 6 hours straight or more and they recharge rapidly. Super simple to set up, just press the button for a second on each one after they are plugged in and BAM done. I let the battery run down to see how it performed at low battery... Very well till the last couple of seconds when it crackled out. As with most devices you must unplug the TX and RX when you are done or they will drain

Battery life is short...

Sounds perfect, no distortion or interference or anything, easy to charge and sync

Stopped working in a few days. Does not connect to wireless signal. Less distance capacity

The updated review:After a bit of sleuthing I found a service email address...one that I posted down below. It took a couple days, but they responded and were very agreeable to my concerns.Full disclosure, my initial email to swiff did include an image of my issue, and the paid invoice from Amazon...so they knew I was a legit customer.I was asked to send back, via priority mail, the defective units, provide the tracking information, which I sent a copy of the ship label and the tracking number, and provide my address.I received an email within the day that my replacement is being sent via Amazon.I was originally satisfied with this unit, as it works quite well as a practice and backup for my bass.I highly recommend this item, especially after knowing the company stands behind their product.The original review:I didn't want to write this review...I bought this 6 months ago, and it worked very well.I'm a regularly playing musician, and this was getting a good workout weekly.I play bass, and finding a wireless that sounds good at low frequency is already a battle, and this was actually performing quite well.In the last week I realized the receiver was not holding a charge for more than 45 minutes.At first I thought it was me...maybe I forgot to turn the unit off, maybe my charge cable wasn't plugged in correctly.Over the course of a week I tested my charge time, made sure both units were charging to full, etc.Unfortunately, the receiver is dead...and when I play for up to 3-4 hours per gig, practice sessions, and rehearsals, I cant afford to have this unit die.It's not the most expensive unit, but I also have units from the competition, such as Getaria, and Lekato, that are older, with weaker specs, and still hold a nice long charge beyond the factory claims.My item is outside of the return window, and therefore I attempted to identify Swiff's customer service from the company website. The email addresses I found; [email protected] and [email protected] have been sent back as undeliverable.It's not an expensive piece of equipment, but I also hoped it would last more than 6 months.Buyer beware.
