Never had trouble with this one
It requires the resistor divider which is a pain, but works at 9600 without doing anything.

Good but AT command button didn't work
The AT button didn't work for me to put it into AT command mode. In the reviews there was another poster that had the se issue. He linked to a site that worked to put it into AT command.

Simple way to get serial-to-bluetooth passthru, but cheaper HC-06 may be better.
I bought two HC-05s from DSD TECH, both at slightly different prices and descriptions. The modules both have a button which is used to enter command mode on power up. The color of the antennas was different, and one came with a 6-wire jumper cable, but beyond that they seem to be the same. (See photos.)I needed to switch the baud rate to 115200. I used an Arduino to do this with simple code to go between the Serial console and a SoftwareSerial set of pins hooked to this module. By holding down the button on power up, the device enters command mode (slow 2-second red LED blink). The baud rate is 38400, and I had to make sure I slowed the Arduino console baud rate down as well else the terminal would send characters faster than could be parsed. This was causing “ERROR:(0)” to be echoed because letters were being dropped.I was able to “AT+BAUD=115200,1,0” and “AT+NAME=HC-05A” to change baud rate and name for the modules, and all is working well.If looking for JUST something to act as a serial pass thru, there is a cheaper 4-pin module that works well. We ended up ordering a dozen of those to use since we don’t really need the master/slave support.(Photos are of the two different DSD TECH modules I ordered.)

Perfectly Classic and works perfectly; firmware is Version: 2.0-20100601
Anyone using these HC-05 modules knows that there are many different hardware and firmware implementations, and they don't all work the same. I don't have extraordinary requirements for this BT module, but I do use it with Arduino and AT commands and set the AT+NAME, AT+UART, and AT+PSWD. Also, I need specific data buffering and blocking when the buffer is full, and have had problems with firmware versions 3.0 and especially 4.0. For this device from DSD Tech the firmware is Version: 2.0-20100601. It works perfectly. It's sold as Classic, and that is how it is perfectly working.

It works; barely.
Old module, not compatible/can't connect with IOS or newer android versions. Easy to setup as any other module. Functionality is limited to a few feet, but solders and overall quality is good.

It works
I'm 1 for 1 on these so far (no DOA or failures). They work as expected and have good range. I'll be back for more.

Works but may be hard to configure.
Kind of a pain to program and change settings on an arduino. Ended up using an hc06 instead since it was simpler for me. If you don't want to change baud rates, PINs, or names, this should do fine for you.

VERY WELL MADE EASY TO USE
IVE ORDERED OTHER MODULES ONLY TO RETURN THEM. But this thing here is amazing. works well, at command mode works well, works how an hc-05 should and well made. Although they dont provide the clear cover i just put some heatshrink on it and called it a day.
