Tello will come back tomorrow from RYZE Japan

I damaged Tello due to power loss landing on beach sands.
Motor is damaged by irony sands.
It occurred on Jan. 27.
Once Tello came back from RYZE repair, but it has another default in WIFI comunication.

I resent the Tello to RYZE on Feb. 13th. then it will come back Jan. 22.

Tello tripped for about 1 month to repair completely.

You must take care you should not do same as me.

• You must avoid power loss landing. You must land the Tello where it can land safe and sounds. Tello main body and propulsions are too near to the ground. The circumstances the ground affect Tello vety much.
• You should know how remote you can Control Tello, watching WIFI analyzer.

Finally I appreciate RYZE.Japan taking care of my Tello, once they sent me default Tello.

Have a good Tello life !

Tello, RYZE.Jpan Tech says repaired one is default!

On

Feb.13 I Sent RYZE. Tech Japan the Tello I received from them after repair.

Feb.14 They have received it from me.

Feb.16 They are silent without any excuse nor apologize.
I am sure that they sent default Tello erroneously ss repair.
So I sent them email that your repair is incomplete,so you had better respond to my request prior to others.l

Feb. 18 They emails that they open my Tello Package.
That means they begin inspect the Tello I sent, which also they sent me as repair conclusion.

Feb,20 They informed me that they will repair Tello without any charge this tine. That means they admit they mistook in previous Tello repair.

Details are the folloeings.

• Inspection result : Comunication Device Error
• Repair needs to exchange the core board unit (including TOF & bottom viewer) of Tello costs 7.8kJPY.
• Discount 7.8kJPY
• It will take about 5days to deliver it, because they shall confirm flight performances outdoor this time.

It takes long hours for me untill they recognize what the matter is about my first Tello repair.

It is good for me and them to understand what the real is.

I hope I can get perfect Tello from RYZE Japan.

Tello, too early to evaluate ！

As soon as I have got Tello from RYZE, RYZE requested me to evaluate evaluate them on their repair by email.

Unfortunately I should evaluate this repair minimum and subscribed whole stories after I received it in their WEB.

Because repair is noy satisfactory.

But sorry to me, they won't give me any responce.

Usually some clients complained the service matters, they reasonably respond to complaint or apologies.

RYZE is silent for 2 days. Is it mean to evaluate their services for clients?  If they do not improve themselves, it is not meaningfull questionnaire.

Sorry

Tello

Tello is received from me on Feb. 14th, but …

I returned Tello to RYZE Tech center on Feb. 13th.

Because Tello I got from RYZE after repair is inferior than before in its performaces. This seems due to weak WIFI connectivity.

They may have received it from me on Feb.14th.
They say they will infrom me of inspection result of the Tello.

RYZE should consider the former repair case is not completed, then they shuold repair it prior to another repair cases.

Previously it took a week until they opened my Tello up after they received it.

Tello can not fly well after RYZE repair, how worse?

I informed RYZE Japan how replaced Tello can not fly well as before repair.

I will ship it to RYZE repair center to exchange into a right Tello.

I will show you here how present Tello that RYZE Japan sent me, can not fly as same as previous Tello.

• Below 10m high over your head(means no distsnt), Tello sends me warning "Weak WIFI, please let Tello near you!". Although previous Tello does not send warning at 30m high and 50m distsnce.
• Present Tello is unable to control within no far remote from me. If you try to discend it, Tello keeps hovering ignoring command to descend.
• Control smartphone gets black out. You can not receive images Tello should send to your iphone.
• Uncontrolable drone is very dangerous. Finaly smartphone wifi automatically shut down connect with present Tello.
• Previous Tello can fly well 100m dist x 30m high.
• Present Tello can not fly within 10m dist x 8m high.

Please compare Present Tello and Previous Tello, watching movies they respectively shot.

The former follwoing 2 movies are taken by Present Tello with sending weak wifi warnings.

Sometimes it is unable to control or it gets black out.
Sometimes movies does not continue or does green out.

It is clear from these movies, I can not fly present Tello ss far as the distant previous can fly.

Previous Tello took movies the followings without sending warning and always controlable.

I had 2 Tellos. Both Tello can fly as well as shown in the movie, at the distance and at the hight as shown in this movie.

Sorry Present Tello should not be able shoot like this one. It can not fly far nor high as this.

This can be done by Tello , I think.

Finaly, I add here WIFi analysis results measured WIFI analysis, android application.

This is shown regarding Present Tello at 1m distance.

 I wonder if it is weaker than WIFI router farer disrant, 3m.

RYZE Tech will send me another Tello .

I hope that does not have WIFI weakness , whici is lack of fully function of drone Tello.

And it is my conclusion, 

Even repair by product organization does not bring previous perfomances of Tello. Because repair by RYZE Tech Japan is not true repair but exchange another Tello.

So you shall  take any risks which new Tello has substantially.

In case of my affair, it may be  better to replace 4 motors damaged by myself.

Tello, intolerable Results of RYZE Japan Repair

On  Feb.9th , Tello came back from RYZE.Japan to me.
It is early I received Tello from RYZE Japan after I shipped Tello to RYZE.
After I received Tello from RYZE Tech , I tried to fly Tello.
But I find it degraded in controlable fly range.

Previous Tello does not send weak wifi warning at 30m high, but this one sends it below 10m high. After repair, flight controlable range becomes narrower as 1/4 in hight. Maybe 1/10 in distance.

I must say complain to RYZE Tech Japan about this unsatisfactory results of their repair and ask them repair my old Tello main body with motors replace again.

Why does this unsatisfactory repair event occur?
That is,I suppose,
RYZE Tech Japan did not repair my Tello which required to replace damaged 4 motors.
Instead repair needed to replace 4 motors, RYZE Tech Japan sent me another Tello main body. It is sure that they inform me new main body S/N number.

For them this method, that is no repair customer's one but only exchange to another one , eliminates work hours  then work cost.It will be full advatageous for them.

But customer should take any risk of inferior perfomance difference individual Tello mainbody has.

For me, it is true that Tello is now worse than before although RYZE Japan repaired.

Every Tello does not have same performaces.
For me, new Tello is clearly inferior to my old one in WIFI comunication.
After repair, Tello can now have controlable are 20m dist. X 7m high.
Clearly RYZE Tech Japan`s repair degrades my Tello.
If they did repair my old one as story as they told me, this degrade should not occur.

I hope RYZE Japan do repair as they informed me.
