Here is one positive review from Keven M., a happy customer who bought this unit:

After researching tankless systems, and consulting several plumbers I do business with, I took a leap of faith and bought the Bosch 2700ES. Let me tell you .. amazing is the best thing I can tell you! Our home is a 4 bedroom/ 3 full bath with 2 teenagers, my wife, and myself. First morning I was a little nervous jumping into the shower as my wife was already in the shower upstairs, but like everything else Bosch we own, it stood the test, and the water was sizzling! (Keven M.)

And here is one negative review from John K:

had a problem with the gas valve on new heater, when Bosch found out i bought it from Amazon.com they said they would not honor warranty. I needed hot water so i had them send a new gas valve which i paid for ( $ 260.00 ) they sent wrong part. As of a week and a half latter i still do not have hot water. Would never buy a Bosch appliance or tool again. This company has been inpossible to deal with. 19 phone calls and no hot water and they could care less.

Another reviewer (Jason D.) is giving his advice:

“Microswitch can prevent igniter from sparking– easy fix!”
If there is no clicking sound, it almost always means the main ignition or control unit (box with red and green lights and wires coming from it) is not getting the supply voltage. The voltage is supplied by a generator that is getting energy from the flow of water (the “hydro generator”). First, disconnect the wire connector at the hydro-generator and check the voltage while water is running.. If you have at least 1 VAC, then check the “microswitch” that allows the hydro-generator voltage to reach the ignition unit. To check it, disconnect the other wire connector that is on the black wire coming from the hydrogenerator that is closer to the ignition unit. Then, with the water running, stick a small screwdriver in the male plug side to short the two wires in order to bypass the microswitch (per Bosch tech support instructions). You should now hear clicking and see the unit work…
